Persian belongs to the Indo-European language family, and many words in modern Persian usage ultimately originate from Proto-Indo-European. The language makes extensive use of word building techniques such as affixation and compounding to derive new words from roots. Persian has also had considerable contact with other languages, resulting in many borrowings.
Native word formation
Persian is very powerful in word building and versatile in ways a word can be built from combining affixes, stems, nouns and adjectives. Having many affixes to form new words (over a hundred), and the ability to build affixes and specially prefixes from nouns, The Persian language is also claimed to be and demonstrated as an agglutinative language since it also frequently uses derivational agglutination to form new words from nouns, adjectives, and verbal stems. New words are also extensively formed by compounding – two existing words combining into a new one, as is common in German, Sanskrit and hence most of the Indian languages. Professor Mahmoud Hessaby demonstrated that Persian can derive more than 226 million words.
