Zero copula

In English

Standard English exhibits a few limited forms of the zero copula. One is found in comparative correlatives like "the higher, the better" and "the more the merrier". However, no known language lacks this structure (aside from the invented language Toki Pona), and it is not clear how a comparative is joined with its correlate in this kind of copula. Zero copula also appears in casual questions and statements like "you from out of town?" and "enough already!" where the verb (and more) may be omitted due to syncope. It can also be found, in a slightly different and more regular form, in the headlines of English newspapers, where short words and articles are generally omitted to conserve space. For example, a headline would more likely say "Parliament at a standstill" than "Parliament is at a standstill". Because headlines are generally simple, in "A is B" statements, an explicit copula is rarely necessary.

The zero copula is far more common in some varieties of Caribbean creoles and African American Vernacular English, where phrases like "where you at?", and "who she?" can occur. As in Russian and Arabic, the copula can only be omitted in the present tense; the copula can only be omitted in African American Vernacular English where it can be contracted in Standard American English.

In other languages

Omission frequently depends on the tense and use of the copula.

Russian

In Russian the copula быть (byt’) is normally omitted in the present tense, but not in the past tense:

Present (omitted):

Past (used):

The third person plural суть (sut’, "are") is still used in some standard phrases, but since it is a homonym of the noun "essence", most native speakers do not notice it to be a verb:

The verb быть (byt’) is the infinitive of "to be". The third person singular, есть (yest’) means "is" (and, interestingly enough, it is a homophone of the infinitive "to eat"). As a copula, it can be inflected into the past (был, byl), future (будет, budet), and conditional (был бы, byl by) forms. A present tense (есть, yest’) exists; however, it is almost never used as a copula, but rather omitted altogether or replaced by the verb являться (yavlyat'sa, "to be in essence"). Thus one can say:

But not usually:

But in some cases the verb быть in the present tense (form есть) is employed: Будь тем, кто ты есть (Be who you are).

The present tense of the copula in Russian was in common use well into the 19th century (as attested in the works of Fyodor Dostoyevsky) but is now used only for archaic effect.

Turkic languages

There is a contrast between regular verb "to be" (olmak) and copulative/auxiliary verb "to be" (imek) in Turkish.

Auxiliary verb imek shows its existence only through suffixes to predicates that can be nouns, adjectives or arguably conjugated verb stems, arguably being the only irregular verb in Turkish. In the third person, zero copula is the rule, as in Hungarian or Russian. For example:

The essential copula is possible in third person singular:

In Tatar, dir expresses doubt rather than a characteristic. The origin of dir is the verb durmak, with a similar meaning to the Latin stare.

Japanese

In Japanese, the copula is not used with predicative adjectives, such as gohan wa atsui (ご飯は熱い, [the] food [is] hot). It is sometimes omitted with predicative nouns and adjectival nouns in non-past tense, such as keitai wa benri (携帯は便利[だ], mobile phones [are] convenient), but is necessary for marking past tense or negation, as in ii keiken datta (いい経験だった, [it] was [a] good experience). It is also sometimes omitted in wh-questions, such as nani kore? (何これ？, what [is] this?).

Māori

In Māori, the zero copula can be used in predicative expressions and with continuous verbs (many of which take a copulative verb in many Indo-European languages) — He nui te whare, literally "a big the house", "the house (is) big"; I te tēpu te pukapuka, literally "at (past locative particle) the table the book", "the book (was) on the table"; Nō Ingarangi ia, literally "from England (s)he", "(s)he (is) from England"; Kei te kai au, literally "at the (act of) eating I", "I (am) eating"

Arabic

In Arabic, a Semitic language, the use of the zero copula again depends on the context. In the present tense affirmative, when the subject is definite and the predicate is indefinite, the subject is simply juxtaposed with its predicate. When both the subject and the predicate are definite, a pronoun (agreeing with the subject) must be inserted between the two. For example:

The extra pronoun is needed to prevent the adjective qualifying the noun attributively:

(This is just a noun phrase with no copula. See al- for more on the use of definite and indefinite nouns in Arabic and how it affects the copula.)

In the past tense, however, or in the present tense negative, the verbs kāna and laysa are used, which take the accusative case:

When the copula is expressed with a verb, no pronoun need be inserted, regardless of the definiteness of the predicate:

Hebrew, another Semitic language, uses zero copula in a very similar way.

Ganda

The Ganda verb "to be", -li, is used in only two cases: when the predicate is a prepositional phrase and when the subject is a pronoun and the predicate is an adjective:

Otherwise, the zero copula is used:

Here the word mulungi, "beautiful" is missing its initial vowel pre-prefix o-. If included, it would make the adjective qualify the noun omuwala attributively:

American Sign Language

American Sign Language does not have a copula. For example, "my hair is wet" is signed my hair wet, and "my name is Pete" may be signed [I NAME]^topic P-E-T-E.

Irish

The copula is is used in Irish but may be omitted in the present tense. For example, Is fear mór é ("He is a big man") can be expressed as simply Fear mór é. The common phrase Pé scéal é (meaning "anyhow", lit. "Whatever story it [is]") also omits the copula.

Welsh

The fact that Welsh often requires the use of a predicative particle to denote non-definite predicates means that the copula can be omitted in certain phrases. For example, the phrase Ac yntau'n ddyn byr... ("Since he is/was/etc. a short man...") literally translates as "And he [particle] a short man...". The zero copula is especially common in Welsh poetry of the gogynfardd style.

Amerindian languages

Nahuatl, as well as some other Amerindian languages, has no copula. Instead of using a copula, it is possible to conjugate nouns or adjectives like verbs.

Grammarians and other comparative linguists, however, do not consider this to constitute a zero copula but rather an affixal copula. Affixal copulae are not unique to Amerindian languages but can be found, for instance, in Korean and in the Eskimo languages.

Many indigenous languages of South America do, however, have true zero copulae in which no overt free or bound morpheme is present when one noun is equated with another.
