Portuguese language

History

When the Romans arrived in the Iberian Peninsula in 216 BCE, they brought the Latin language with them, from which all Romance languages descend. The language was spread by Roman soldiers, settlers, and merchants, who built Roman cities mostly near the settlements of previous Celtic or Celtiberian civilizations established long before the Roman arrivals.

Between 409 CE and 711 CE, as the Roman Empire collapsed in Western Europe, the Iberian Peninsula was conquered by Germanic peoples (Migration Period). The occupiers, mainly Suebi and Visigoths who originally spoke Germanic languages, quickly adopted late Roman culture and the Vulgar Latin dialects of the peninsula and over the next 300 years totally integrated in the local populations. After the 711/Moorish invasion, Arabic became the administrative and common language in the conquered regions, but most of the remaining Christian population continued to speak a form of Romance commonly known as Mozarabic, which lasted three centuries longer in Spain.

Portuguese evolved from the medieval language, known today by linguists as Galician-Portuguese, Old Portuguese or Old Galician, of the northwestern medieval Kingdom of Galicia. It is in Latin administrative documents of the 9th century that written Galician-Portuguese words and phrases are first recorded. This phase is known as Proto-Portuguese, which lasted from the 9th century until the 12th-century independence of the County of Portugal from the Kingdom of León, by then reigning over Galicia.

In the first part of the Galician-Portuguese period (from the 12th to the 14th century), the language was increasingly used for documents and other written forms. For some time, it was the language of preference for lyric poetry in Christian Hispania, much as Occitan was the language of the poetry of the troubadours in France. Portugal became an independent kingdom in 1139, under King Afonso I of Portugal. In 1290, King Denis of Portugal created the first Portuguese university in Lisbon (the Estudos Gerais, which later moved to Coimbra) and decreed for Portuguese, then simply called the "common language", to be known as the Portuguese language and used officially.

In the second period of Old Portuguese, in the 15th and 16th centuries, with the Portuguese discoveries, the language was taken to many regions of Africa, Asia and the Americas. By the mid-16th century, Portuguese had become a lingua franca in Asia and Africa, used not only for colonial administration and trade but also for communication between local officials and Europeans of all nationalities.

Its spread was helped by mixed marriages between Portuguese and local people and by its association with Roman Catholic missionary efforts, which led to the formation of creole languages such as that called Kristang in many parts of Asia (from the word cristão, "Christian"). The language continued to be popular in parts of Asia until the 19th century. Some Portuguese-speaking Christian communities in India, Sri Lanka, Malaysia, and Indonesia preserved their language even after they were isolated from Portugal.

The end of the Old Portuguese period was marked by the publication of the Cancioneiro Geral by Garcia de Resende, in 1516. The early times of Modern Portuguese, which spans the period from the 16th century to the present day, were characterized by an increase in the number of learned words borrowed from Classical Latin and Classical Greek because of the Renaissance, which greatly enriched the lexicon.

Geographic distribution

Portuguese is the language of the majority of people in Brazil and Portugal, and 99.8% of the population of São Tomé and Príncipe declared speaking Portuguese in the 1991 census. Perhaps 75% of the population of Angola speaks Portuguese natively, and 85% are fluent. Just over 40% of the population of Mozambique are native speakers of Portuguese, and 60% are fluent, according to the 2007 census. Portuguese is also spoken natively by 30% of the population in Guinea-Bissau, and a Portuguese-based creole is understood by all. No data is available for Cape Verde, but almost all the population is bilingual, and the monolingual population speaks Cape Verdean Creole.

There are also significant Portuguese speaking immigrant communities in many countries including Andorra (15.4%), Bermuda, Canada (0.72% or 219,275 people in the 2006 census), France (500,000 people), Japan (400,000 people), Jersey, Namibia (about 4–5% of the population, mainly refugees from Angola in the North of the country), Paraguay (10.7% or 636,000 people), Macau (0.6% or 12,000 people), Switzerland (196,000 nationals in 2008), Venezuela (254,000). and the United States (0.35% of the population or 1,228,126 speakers according to the 2007 American Community Survey),

In some parts of former Portuguese India, namely Goa and Daman and Diu, the language is still spoken by about 10,000 people. In 2014, an estimated 1,500 students were learning Portuguese in Goa.

Official status

The Community of Portuguese Language Countries (in Portuguese Comunidade dos Países de Língua Portuguesa, with the Portuguese acronym CPLP) consists of the eight independent countries that have Portuguese as an official language: Angola, Brazil, Cape Verde, East Timor, Equatorial Guinea, Guinea-Bissau, Mozambique, Portugal and São Tomé and Príncipe.

Equatorial Guinea made a formal application for full membership to the CPLP in June 2010, a status given only to states with Portuguese as an official language. In 2011, Portuguese became its third official language (besides Spanish and French) and, in July 2014, the country was accepted as a member of the CPLP.

Portuguese is also one of the official languages of the Special Administrative Region of the People's Republic of China of Macau (alongside Chinese) and of several international organizations, including the Mercosur, the Organization of Ibero-American States, the Union of South American Nations, the Organization of American States, the African Union, the Economic Community of West African States, the Southern African Development Community and the European Union.

Population of countries and jurisdictions of Portuguese official or co-official language

According to The World Factbook country population estimates for 2016, the population of each of the nine jurisdictions is as follows (by descending order):

This means that the population living in the Lusophone official area is of 272,918,286 inhabitants. This number does not include the Lusophone diaspora, estimated at approximately 10 million people (including 4.5 million Portuguese, 3 million Brazilians, and half a million Cape Verdeans, among others), although it is hard to obtain official accurate numbers of diasporic Portuguese speakers because a significant portion of these citizens are naturalized citizens born outside of Lusophone territory or are children of immigrants, and may have only a basic command of the language. It is also important to note that a large part of the diaspora is a part of the already-counted population of the Portuguese-speaking countries and territories, such as the high number of Brazilian and PALOP emigrant citizens in Portugal or the high number of Portuguese emigrant citizens in the PALOP and Brazil.

The Portuguese language therefore serves more than 250 million people daily, who have direct or indirect legal, juridical and social contact with it, varying from the only language used in any contact, to only education, contact with local or international administration, commerce and services or the simple sight of road signs, public information and advertising in Portuguese.

Portuguese as a foreign language

The mandatory offering of Portuguese language in school curricula is observed in Uruguay and Argentina. Other countries where Portuguese is taught at schools or is being introduced now include Venezuela, Zambia, the Republic of the Congo, Senegal, Namibia, Swaziland, and South Africa.

Future

According to estimates by UNESCO, Portuguese is the fastest-growing European language after English and the language has, according to the newspaper The Portugal News publishing data given from UNESCO, the highest potential for growth as an international language in southern Africa and South America. Portuguese is a globalized language spoken officially in 5 continents, and as a second language by millions worldwide.

Since 1991, when Brazil signed into the economic community of Mercosul with other South American nations, namely Argentina, Uruguay and Paraguay, Portuguese is either mandatory, or taught, in the schools of those South American countries.

Although early in the 21st century, after Macau was ceded to China and Brazilian immigration to Japan slowed down, the use of Portuguese was in decline in Asia, it is once again becoming a language of opportunity there, mostly because of increased diplomatic and financial ties with Portuguese-speaking countries in China, but also some interest in their cultures, mainly Koreans and Japanese about Brazil. Presently China is doing a great amount of trade with all of the Portuguese speaking countries, and the Chinese themselves are learning Portuguese. These factors bode very well for the continued growth of Portuguese as an important economic, international language.

Dialects

Você is used for educated, formal and colloquial respectful speech in most Portuguese-speaking regions. In the Brazilian state of Rio Grande do Sul, você is virtually absent from the spoken language. In Portugal, it is considered rude to treat someone as você, so the pronoun is either replaced by the name of the person (or a title) or it is omitted, since the verbal conjugation allows the distinction between formal and informal treatment. Riograndense (or Gaúcho) Portuguese normally distinguishes formal from informal speech by verbal conjugation. Informal speech employs tu followed by third person verbs, formal language retains the traditional second person.

Conjugation of tu has three different forms in Brazil (verb "to see": tu viste?, in the traditional second person, tu viu?, in the third person, and tu visse?, in the innovative second person), the conjugation used in the Brazilian states of Pará, Santa Catarina and Maranhão being generally traditional second person, the kind that is used in other Portuguese-speaking countries and learned in Brazilian schools.

The predominance of Southeastern-based media products has established você as the pronoun of choice for the second person singular in both writing and multimedia communications. However, in the city of Rio de Janeiro, the country's main cultural centre, the usage of tu has been expanding ever since the end of the 20th century (see [7], a linguistic research on the topic in Portuguese), being most frequent among youngsters and a number of studies have also shown an increase in its use in a number of other Brazilian dialects [8][9].

Modern Standard European Portuguese (português padrão or português continental) is based on the Portuguese spoken in the area including and surrounding the cities of Coimbra and Lisbon, in central Portugal. Standard European Portuguese is also the preferred standard by the Portuguese-speaking African countries. As such, and despite the fact that its speakers are dispersed around the world, Portuguese has only two dialects used for learning: the European and the Brazilian. Some aspects and sounds found in many dialects of Brazil are exclusive to South America, and cannot be found in Europe. However, the Santomean Portuguese in Africa may be confused with a Brazilian dialect by its phonology and prosody.

Audio samples of some dialects and accents of Portuguese are available below. There are some differences between the areas but these are the best approximations possible. IPA transcriptions refer to the names in local pronunciation.

Brazil

1. Caipira — Spoken in the states of São Paulo (most markedly on the countryside and rural areas); southern Minas Gerais, northern Paraná and southeastern Mato Grosso do Sul. Depending on the vision of what constitutes caipira, Triângulo Mineiro, border areas of Goiás and the remaining parts of Mato Grosso do Sul are included, and the frontier of caipira in Minas Gerais is expanded further northerly, though not reaching metropolitan Belo Horizonte. It is often said that caipira appeared by decreolization of the língua brasílica and the related língua geral paulista, then spoken in almost all of what is now São Paulo, a former lingua franca in most of the contemporary Centro-Sul of Brazil before the 18th century, brought by the bandeirantes, interior pioneers of Colonial Brazil, closely related to its northern counterpart Nheengatu, and that is why the dialect shows many general differences from other variants of the language. It has striking remarkable differences in comparison to other Brazilian dialects in phonology, prosody and grammar, often stigmatized as being strongly associated with a substandard variant, now mostly rural.
2. Cearense or Costa norte — is a dialect spoken more sharply in the states of Ceará and Piauí. The variant of Ceará includes fairly distinctive traits it shares with the one spoken in Piauí, though, such as distinctive regional phonology and vocabulary (for example, a debuccalization process stronger than that of Portuguese, a different system of the vowel harmony that spans Brazil from fluminense and mineiro to amazofonia but is especially prevalent in nordestino, a very coherent coda sibilant palatalization as those of Portugal and Rio de Janeiro but allowed in fewer environments than in other accents of nordestino, a greater presence of dental stop palatalization to palato-alveolar in comparison to other accents of nordestino, among others, as well as a great number of archaic Portuguese words).
3. Baiano — Found in Bahia, Sergipe, northern Minas Gerais and border regions with Goiás and Tocantins. Similar to nordestino, it has a very characteristic syllable-timed rhythm and the greatest tendency to pronounce unstressed vowels as open-mid [ɛ] and [ɔ].
4. Fluminense — A broad dialect with many variants spoken in the states of Rio de Janeiro, Espírito Santo and neighbouring eastern regions of Minas Gerais. Fluminense formed in these previously caipira-speaking areas due to the gradual influence of European migrants, causing many people to distance their speech from their original dialect and incorporate new terms. Fluminense is sometimes referred to as carioca, however carioca is a more specific term referring to the accent of the Greater Rio de Janeiro area by speakers with a fluminense dialect.
5. Gaúcho — in Rio Grande do Sul, similar to sulista. There are many distinct accents in Rio Grande do Sul, mainly due to the heavy influx of European immigrants of diverse origins who have settled in colonies throughout the state, and to the proximity to Spanish-speaking nations. The gaúcho word in itself is a Spanish loanword into Portuguese of obscure Indigenous Amerindian origins.
6. Mineiro — Minas Gerais (not prevalent in the Triângulo Mineiro). As the fluminense area, its associated region was formerly a sparsely populated land where caipira was spoken, but the discovery of gold and gems made it the most prosperous Brazilian region, what attracted Portuguese colonists, commoners from other parts of Brazil and their African slaves. South-southwestern, southeastern and northern areas of the state have fairly distinctive speech, actually approximating to caipira, fluminense (popularly called, often pejoratively, carioca do brejo, "marsh carioca") and baiano respectively. Areas including and surrounding Belo Horizonte have a distinctive accent.
7. Nordestino — more marked in the Sertão (7), where, in the 19th and 20th centuries and especially in the area including and surrounding the sertão (the dry land after Agreste) of Pernambuco and southern Ceará, it could sound less comprehensible to speakers of other Portuguese dialects than Galician or Rioplatense Spanish, and nowadays less distinctive from other variants in the metropolitan cities along the coasts. It can be divided in two regional variants, one that includes the northern Maranhão and southern of Piauí, and other that goes from Ceará to Alagoas.
8. Nortista or amazofonia — Most of Amazon Basin states i.e. Northern Brazil. Before the 20th century, most people from the nordestino area fleeing the droughts and their associated poverty settled here, so it has some similarities with the Portuguese dialect there spoken. The speech in and around the cities of Belém and Manaus has a more European flavor in phonology, prosody and grammar.
9. Paulistano — Variants spoken around Greater São Paulo in its maximum definition and more easterly areas of São Paulo state, as well perhaps "educated speech" from anywhere in the state of São Paulo (where it coexists with caipira). Caipira is the hinterland sociolect of much of the Central-Southern half of Brazil, nowadays conservative only in the rural areas and associated with them, that has a historically low prestige in cities as Rio de Janeiro, Curitiba, Belo Horizonte, and until some years ago, in São Paulo itself. Sociolinguistics, or what by times is described as 'linguistic prejudice', often correlated with classism, is a polemic topic in the entirety of the country since the times of Adoniran Barbosa. Also, the "Paulistano" accent was heavily influenced by the presence of immigrants in the city of São Paulo, especially the Italians.
10. Sertanejo — Center-Western states, and also much of Tocantins and Rondônia. It is closer to mineiro, caipira, nordestino or nortista depending on the location.
11. Sulista — The variants spoken in the areas between the northern regions of Rio Grande do Sul and southern regions of São Paulo state, encompassing most of southern Brazil. The city of Curitiba does have a fairly distinct accent as well, and a relative majority of speakers around and in Florianópolis also speak this variant (many speak florianopolitano or manezinho da ilha instead, related to the European Portuguese dialects spoken in Azores and Madeira). Speech of northern Paraná is closer to that of inland São Paulo.
12. Florianopolitano — Variants heavily influenced by European Portuguese spoken in Florianópolis city (due to a heavy immigration movement from Portugal, mainly its insular regions) and much of its metropolitan area, Grande Florianópolis, said to be a continuum between those whose speech most resemble sulista dialects and those whose speech most resemble fluminense and European ones, called, often pejoratively, manezinho da ilha.
13. Carioca — Not a dialect, but sociolects of the fluminense variant spoken in an area roughly corresponding to Greater Rio de Janeiro. It appeared after locals came in contact with the Portuguese aristocracy amidst the Portuguese royal family fled in the early 19th century. There is actually a continuum between Vernacular countryside accents and the carioca sociolect, and the educated speech (in Portuguese norma culta, which most closely resembles other Brazilian Portuguese standards but with marked recent Portuguese influences, the nearest ones among the country's dialects along florianopolitano), so that not all people native to the state of Rio de Janeiro speak the said sociolect, but most carioca speakers will use the standard variant not influenced by it that is rather uniform around Brazil depending on context (emphasis or formality, for example).
14. Brasiliense — used in Brasília and its metropolitan area. It is not considered a dialect, but more of a regional variant – often deemed to be closer to fluminense than the dialect commonly spoken in most of Goiás, sertanejo.
15. Arco do desflorestamento or serra amazônica — Known in its region as the "accent of the migrants", it has similarities with caipira, sertanejo and often sulista that make it differing from amazofonia (in the opposite group of Brazilian dialects, in which it is placed along nordestino, baiano, mineiro and fluminense). It is the most recent dialect, which appeared by the settlement of families from various other Brazilian regions attracted by the cheap land offer in recently deforested areas.
16. Recifense — used in Recife and its metropolitan area.

Portugal

1. Micaelense (Açores) (São Miguel)—Azores.
2. Alentejano—Alentejo (Alentejan Portuguese)
3. Algarvio—Algarve (there is a particular dialect in a small part of western Algarve).
4. Minhoto—Districts of Braga and Viana do Castelo (hinterland).
5. Beirão; Alto-Alentejano—Central Portugal (hinterland).
6. Beirão— Central Portugal.
7. Estremenho—Regions of Coimbra, Leiria and Lisbon (this is a disputed denomination, as Coimbra is not part of "Estremadura", and the Lisbon dialect has some peculiar features that not only are not shared with the one of Coimbra, but also are significantly distinct and recognizable to most native speakers from elsewhere in Portugal).
8. Madeirense (Madeiran)—Madeira.
9. Portuese—Regions of the district of Porto and parts of Aveiro.
10. Transmontano—Trás-os-Montes e Alto Douro.

Other countries and dependencies

Differences between dialects are mostly of accent and vocabulary, but between the Brazilian dialects and other dialects, especially in their most colloquial forms, there can also be some grammatical differences. The Portuguese-based creoles spoken in various parts of Africa, Asia, and the Americas are independent languages.

Characterization and peculiarities

Portuguese, like Catalan, preserved the stressed vowels of Vulgar Latin, which became diphthongs in most other Romance languages; cf. Port., Cat., Sard. pedra ; Fr. pierre, Sp. piedra, It. pietra, Ro. piatră, from Lat. petra ("stone"); or Port. fogo, Cat. foc, Sard. fogu; Sp. fuego, It. fuoco, Fr. feu, Ro. foc, from Lat. focus ("fire"). Another characteristic of early Portuguese was the loss of intervocalic l and n, sometimes followed by the merger of the two surrounding vowels, or by the insertion of an epenthetic vowel between them: cf. Lat. salire ("to jump"), tenere ("to hold"), catena ("chain"), Sp. salir, tener, cadena, Port. sair, ter, cadeia.

When the elided consonant was n, it often nasalized the preceding vowel: cf. Lat. manum ("hand"), ranam ("frog"), bonum ("good"), Port. mão, rãa, bõo (now mão, rã, bom). This process was the source of most of the language's distinctive nasal diphthongs. In particular, the Latin endings -anem, -anum and -onem became -ão in most cases, cf. Lat. canis ("dog"), germanus ("brother"), ratio ("reason") with Modern Port. cão, irmão, razão, and their plurals -anes, -anos, -ones normally became -ães, -ãos, -ões, cf. cães, irmãos, razões.

The Portuguese language is also the only Romance language that developed the clitic case mesoclisis: cf. dar-te-ei (I'll give thee), amar-te-ei (I'll love you), contactá-los-ei (I'll contact them). It was also the only Romance language to retain the Latin synthetic pluperfect tense: eu estivera (I had been), eu vivera (I had lived), vós vivêreis (you had lived).

Vocabulary

Most of the lexicon of Portuguese is derived, directly or through other Romance languages, from Latin. Nevertheless, because of its original Celtiberian heritage and later the participation of Portugal in the Age of Discovery, it has some Gallaecian words and adopted loanwords from all over the world.

A number of Portuguese words can still be traced to the pre-Roman inhabitants of Portugal, which included the Gallaeci, Lusitanians, Celtici and Cynetes. Most of these words derived from Celtic and are very often shared with Galician since both languages share a common origin in the medieval language of Galician-Portuguese. A few of these words existed in Latin as loanwords from a Celtic source, often Gaulish. Altogether these are over 1,000 words, some verbs and toponymic names of towns, rivers, utensils and plants.

In the 5th century, the Iberian Peninsula (the Roman Hispania) was conquered by the Germanic Suebi and Visigoths. As they adopted the Roman civilization and language, however, these people contributed with some 500 Germanic words to the lexicon. Many of these words are related to warfare—such as espora "spur", estaca "stake", and guerra "war", from Gothic *spaúra, *stakka, and *wirro, respectively. The Germanic languages influence also exists in toponymic surnames and patronymic surnames borne by Visigoth sovereigns and their descendants, and it dwells on placenames such has Ermesinde, Esposende and Resende where sinde and sende are derived from the Germanic "sinths" (military expedition) and in the case of Resende, the prefix re comes from Germanic "reths" (council). Other examples of Portuguese names, surnames and town names of Germanic toponymic origin include Henrique, Henriques, Vermoim, Mandim, Calquim, Baguim, Gemunde, Guetim, Sermonde and many more, are quite common mainly in the old Suebi and later Visigothic dominated regions, covering today's Northern half of Portugal and Galicia.

Between the 9th and early 13th centuries, Portuguese acquired nearly 800 words from Arabic by influence of Moorish Iberia.They are often recognizable by the initial Arabic article a(l)-, and include many common words such as aldeia "village" from الضيعة alḍai`a (or from Edictum Rothari: aldii, aldias), alface "lettuce" from الخس alkhass, armazém "warehouse" from المخزن almakhzan, and azeite "olive oil" from الزيت azzait.

Starting in the 15th century, the Portuguese maritime explorations led to the introduction of many loanwords from Asian languages. For instance, catana "cutlass" from Japanese katana and chá "tea" from Chinese chá.

From the 16th to the 19th centuries, because of the role of Portugal as intermediary in the Atlantic slave trade, and the establishment of large Portuguese colonies in Angola, Mozambique, and Brazil, Portuguese acquired several words of African and Amerind origin, especially names for most of the animals and plants found in those territories. While those terms are mostly used in the former colonies, many became current in European Portuguese as well. From Kimbundu, for example, came kifumate > cafuné "head caress" (Brazil), kusula > caçula "youngest child" (Brazil), marimbondo "tropical wasp" (Brazil), and kubungula > bungular "to dance like a wizard" (Angola). From South America came batata "potato", from Taino; ananás and abacaxi, from Tupi–Guarani naná and Tupi ibá cati, respectively (two species of pineapple), and pipoca "popcorn" from Tupi and tucano "toucan" from Guarani tucan.

Finally, it has received a steady influx of loanwords from other European languages, especially French and English. These are by far the most important languages when referring to loanwords. There are many examples such as: colchete/crochê "bracket"/"crochet", paletó "jacket", batom "lipstick", and filé/filete "steak"/"slice", rua "street" respectively, from French crochet, paletot, bâton, filet, rue; and bife "steak", futebol, revólver, estoque, folclore, from English beef, football, revolver, stock, folklore.

Examples from other European languages: macarrão "pasta", piloto "pilot", carroça "carriage", and barraca "barrack", from Italian maccherone, pilota, carrozza, and baracca; melena "hair lock", fiambre "wet-cured ham" (in Portugal, in contrast with presunto "dry-cured ham" from Latin prae-exsuctus "dehydrated") or "canned ham" (in Brazil, in contrast with non-canned, wet-cured presunto cozido and dry-cured presunto cru), and castelhano "Castilian", from Spanish melena "mane", fiambre and castellano.

Before the last four decades, Brazilians adopted a greater number of loanwords from Japanese and other European languages (due to the historical immigration affecting their demographics), and they were and are also more willing to adopt foreign terms that come from globalization than the Portuguese, while the degree of African, Tupian and other Amerindian lexicon in Brazilian Portuguese is shown to be surprisingly lesser than that commonly expected of the said variant by the local Africanist and Indianist academia (that also has to some degree influenced the common sense of what gives a different cultural identity of Brazilians in relation to the Portuguese), so that its lexicon is almost identical (about 99%) to that of European Portuguese.

Many Portuguese settlers to Colonial Brazil were from northern and insular Portugal, apart from some historically important illegal immigrants from elsewhere in Europe, such as Galicia, France and the Netherlands. It should be noted that Brazil received more European immigrants in its colonial history than the United States. Between 1500 and 1760, 700,000 Europeans (overwhelmingly Portuguese) settled in Brazil, while 530,000 Europeans settled in the United States for the same given time.

Classification and related languages

Portuguese belongs to the West Iberian branch of the Romance languages, and it has special ties with the following members of this group:

Portuguese and other Romance languages (namely French and Italian) are not mutually intelligible, although they share considerable similarities in both vocabulary and grammar. Portuguese speakers will usually need some formal study before attaining strong comprehension in those Romance languages, and vice versa. However, Portuguese and Galician are mutually intelligible. Given that Portuguese has a larger phonemic inventory than Spanish, Portuguese is only moderately intelligible to some Spanish speakers, despite the strong lexical and grammatical similarity (89%) between the two.

Portunhol, a form of code-switching, has a more lively use and is more readily mentioned in popular culture in South America. Said code-switching is not to be confused with the portunhol spoken on the borders of Brazil with Uruguay (dialeto do pampa) and Paraguay (dialeto dos brasiguaios), and of Portugal with Spain (barranquenho), that are Portuguese dialects spoken natively by thousands of people, which have been heavily influenced by Spanish.

Portuguese and Spanish are the only Ibero-Romance languages, and perhaps the only Romance languages with such thriving inter-language forms, in which visible and lively bilingual contact dialects and code-switching have formed, in which functional bilingual communication is achieved through attempting an approximation to the target foreign language (known as 'Portunhol') without a learned acquisition process, but nevertheless facilitates communication. There is an emerging literature focused on such phenomena (including informal attempts of standardization of the linguistic continua and their usage).

Galician-Portuguese in Spain

The closest relative of Portuguese is Galician, which is spoken in the autonomous community (region) of Galicia (northwestern Spain). The two were at one time a single language, known today as Galician-Portuguese, but they have diverged especially in pronunciation and vocabulary due to the political separation of Portugal from Galicia. There is, however, still a linguistic continuity consisting of the variant of Galician referred to as galego-português baixo-limiao, which is spoken in several Galician villages between the municipalities of Entrimo and Lobios and the transborder region of the natural park of Peneda-Gerês/Xurês. It is "considered a rarity, a living vestige of the medieval language that ranged from Cantabria to Mondego [...]". As reported by UNESCO, due to the pressure of the Spanish language on the standard official version of the Galician language, the Galician language was on the verge of disappearing. According to the Unesco philologist Tapani Salminen, the proximity to Portuguese protects Galician. Nevertheless, the core vocabulary and grammar of Galician are still noticeably closer to Portuguese than to those of Spanish. In particular, like Portuguese, it uses the future subjunctive, the personal infinitive, and the synthetic pluperfect. Mutual intelligibility (estimated at 90% by R. A. Hall, Jr., 1989) is excellent between Galicians and northern Portuguese. Many linguists consider Galician to be a co-dialect of the Portuguese language.

Another member of the Galician-Portuguese group, most commonly thought of as a Galician dialect, is spoken in the Eonavian region in a western strip in Asturias and the westernmost parts of the provinces of León and Zamora, along the frontier with Galicia, between the Eo and Navia rivers (or more exactly Eo and Frexulfe rivers). It is called eonaviego or gallego-asturiano by its speakers.

The Fala language, known by its speakers as xalimés, mañegu, a fala de Xálima and chapurráu and in Portuguese as a fala de Xálima, a fala da Estremadura, o galego da Estremadura, valego ou galaico-estremenho, is another descendant of Galician-Portuguese, spoken by a small number of people in the Spanish towns of Valverde del Fresno (Valverdi du Fresnu), Eljas (As Ellas) and San Martín de Trevejo (Sa Martín de Trevellu) in the autonomous community of Extremadura, near the border with Portugal.

There is a number of other places in Spain in which the native language of the common people is a descendant of the Galician-Portuguese group, such as La Alamedilla, Cedillo (Cedilho), Herrera de Alcántara (Ferreira d'Alcântara) and Olivenza (Olivença), but in these municipalities, what is spoken is actually Portuguese, not disputed as such in the mainstream.

It should be noticed that the diversity of dialects of the Portuguese language is known since the time of medieval Portuguese-Galician language when it coexisted with the Lusitanian-Mozarabic dialect, spoken in the south of Portugal. The dialectal diversity becomes more evident in the work of Fernão d'Oliveira, in the Grammatica da Lingoagem Portuguesa, (1536), where he remarks that the people of Portuguese regions of Beira, Alentejo, Estremadura, and Entre Douro e Minho, all speak differently from each other. Also Contador d'Argote (1725) distinguishes three main varieties of dialects: the local dialects, the dialects of time, and of profession (work jargon). Of local dialects he highlights five main dialects: the dialect of Estremadura, of Entre-Douro e Minho, of Beira, of Algarve and of Trás-os-Montes. He also makes reference to the overseas dialects, the rustic dialects, the poetic dialect and that of prose.

In the kingdom of Portugal, Ladinho (or Lingoagem Ladinha) was the name given to the pure Portuguese language romance, without any mixture of Aravia or Gerigonça Judenga. While the term língua vulgar was used to name the language before D. Dinis decided to call it "Portuguese language", the erudite version used and known as Galician-Portuguese (the language of the Portuguese court) and all other Portuguese dialects were spoken at the same time. In a historical perspective the Portuguese language was never just one dialect. Just like today there is a standard Portuguese (actually two) among the several dialects of Portuguese, in the past there was Galician-Portuguese as the "standard", coexisting with other dialects.

Influence on other languages

Portuguese has provided loanwords to many languages, such as Indonesian, Manado Malay, Malayalam, Sri Lankan Tamil and Sinhalese, Malay, Bengali, English, Hindi, Swahili, Afrikaans, Konkani, Marathi, Tetum, Xitsonga, Japanese, Lanc-Patuá (spoken in northern Brazil), Esan and Sranan Tongo (spoken in Suriname). It left a strong influence on the língua brasílica, a Tupi–Guarani language, which was the most widely spoken in Brazil until the 18th century, and on the language spoken around Sikka in Flores Island, Indonesia. In nearby Larantuka, Portuguese is used for prayers in Holy Week rituals. The Japanese–Portuguese dictionary Nippo Jisho (1603) was the first dictionary of Japanese in a European language, a product of Jesuit missionary activity in Japan. Building on the work of earlier Portuguese missionaries, the Dictionarium Anamiticum, Lusitanum et Latinum (Annamite–Portuguese–Latin dictionary) of Alexandre de Rhodes (1651) introduced the modern orthography of Vietnamese, which is based on the orthography of 17th-century Portuguese. The Romanization of Chinese was also influenced by the Portuguese language (among others), particularly regarding Chinese surnames; one example is Mei. During 1583–88 Italian Jesuits Michele Ruggieri and Matteo Ricci created a Portuguese–Chinese dictionary—the first ever European–Chinese dictionary.

For instance, as Portuguese merchants were presumably the first to introduce the sweet orange in Europe, in several modern Indo-European languages the fruit has been named after them. Some examples are Albanian portokall, Bulgarian портокал (portokal), Greek πορτοκάλι (portokali), Macedonian portokal, Persian پرتقال (porteghal), and Romanian portocală. Related names can be found in other languages, such as Arabic البرتقال (bourtouqal), Georgian ფორთოხალი (p'ort'oxali), Turkish portakal and Amharic birtukan. Also, in southern Italian dialects (e.g. Neapolitan), an orange is portogallo or purtuallo, literally "(the) Portuguese (one)", in contrast to standard Italian arancia.

Derived languages

Beginning in the 16th century, the extensive contacts between Portuguese travelers and settlers, African and Asian slaves, and local populations led to the appearance of many pidgins with varying amounts of Portuguese influence. As each of these pidgins became the mother tongue of succeeding generations, they evolved into fully fledged creole languages, which remained in use in many parts of Asia, Africa and South America until the 18th century. Some Portuguese-based or Portuguese-influenced creoles are still spoken today, by over 3 million people worldwide, especially people of partial Portuguese ancestry.

Phonology

Portuguese phonology is similar to those of languages such as French (especially that of Quebec), the Gallo-Italic languages, Occitan, Catalan and Franco-Provençal, unlike that of Spanish, which is similar to those of Sardinian and Southern Italian dialects. Some would describe the phonology of Portuguese as a blend of Spanish, Gallo-Romance (e.g. French) and the languages of northern Italy (especially Genoese), but with a deeper Celtic influence.

There is a maximum of 9 oral vowels, 2 semivowels and 21 consonants; though some varieties of the language have fewer phonemes. There are also five nasal vowels, which some linguists regard as allophones of the oral vowels.

Vowels

Like Catalan and German, Portuguese uses vowel quality to contrast stressed syllables with unstressed syllables: isolated vowels tend to be raised, and in some cases centralized, when unstressed.

Grammar

A notable aspect of the grammar of Portuguese is the verb. Morphologically, more verbal inflections from classical Latin have been preserved by Portuguese than by any other major Romance language. The Portuguese and Spanish grammars are very close. It has also some innovations not found in other Romance languages (except Galician and the Fala):

Writing system

Portuguese is written with 26 letters of the Latin script, making use of five diacritics to denote stress, vowel height, contraction, nasalization, and etymological assibilation (acute accent, circumflex, grave accent, tilde, and cedilla). The trema was also formerly used in Brazilian Portuguese, and can still be encountered in words derived from proper names in other languages, such as Anhangüera and mülleriano. Accented characters and digraphs are not counted as separate letters for collation purposes.
