Vietnamese , formerly known under the French colonization as Annamese (see Annam), is the national and official language of Vietnam. It is the mother tongue of the Vietnamese people , who constitute 86% of Vietnam's population, and of about three million overseas Vietnamese, most of whom live in the United States. It is also spoken as a second language by some ethnic minorities of Vietnam. It is part of the Austroasiatic language family, of which it has the most speakers by a significant margin (several times larger than the other Austroasiatic languages put together). Much vocabulary has been borrowed from Chinese, and it was originally written using the Chinese writing system. The Vietnamese writing system in use today is an adapted version of the Latin alphabet, with additional diacritics for tones and certain letters. Vietnamese was identified more than 150 years ago to be part of the Viet-Muong (or Vietic) grouping of the Mon-Khmer branch of the Austroasiatic language family, a family that also includes Khmer, spoken in Cambodia, as well as various tribal and regional languages, such as the Munda languages, spoken in eastern India, and others in southern China. Even though this is supported by etymological comparison , some linguists still believe that Viet-Muong is a separate family, genealogically unrelated to other Mon-Khmer languages. The ancestor of the Vietnamese language was originally based in the area of the Red River in what is now northern Vietnam, and during the subsequent expansion of the Vietnamese language and people into what is now central and southern Vietnam , Vietnamese was linguistically influenced primarily by Chinese, which came to predominate politically in the 2nd century B.C.E. With the rise of Chinese political dominance came radical importation of Chinese vocabulary and grammatical influence. As Chinese was, for a prolonged period, the only medium of literature and government, as well as the primary written language of the ruling class in Vietnam, much of the Vietnamese lexicon in all realms consists of Hán Vi?t (Sino-Vietnamese) words. In fact, as the vernacular language of Vietnam gradually grew in prestige toward the beginning of the second millennium, the Vietnamese language was written using Chinese characters adapted to write Vietnamese, in a similar pattern as used in Japan (kanji), Korea (hanja), and other countries in the Sinosphere. As contact with the West grew, the system of Romanized writing was developed in the 17th century by Portuguese and other Europeans involved in proselytizing and trade in Vietnam. When France invaded Vietnam in the late 19th century, French gradually replaced Chinese as the official language in education and government. Vietnamese adopted many French terms. In addition, many Sino-Vietnamese terms were devised for Western ideas imported through the French. However, the Romanized script did not come to predominate until the beginning of the 20th century, when education became widespread and a simpler writing system was found more expedient for teaching and communication with the general population.

Persian (Farsi) is an Indo-European language spoken in Iran (Persia), Afghanistan, Tajikistan and Uzbekistan. It is derived from the language of the ancient Persian people. Persian and its varieties have official-language status in Iran, Afghanistan, and Tajikistan. According to CIA World Factbook, there are approximately 64 million native speakers of Persian in Iran, Afghanistan, Tajikistan and Uzbekistan and about the same number of people in other parts of the world speak Persian. UNESCO was asked to select Persian as one of its languages in 2006. Persian has been a medium for literary and scientific contributions to the Islamic world as well as the Western. It has had an influence on certain neighbouring languages, particularly the Turkic languages of Central Asia, Caucasus, and Anatolia. It has had a lesser influence on Arabic and other languages of Mesopotamia. For five centuries prior to the British colonization, Persian was widely used as a second language in the Indian subcontinent; it took prominence as the language of culture and education in several Muslim courts in India and became the "official language" under the Mughal emperors. Only in 1843 did the subcontinent begin conducting business in English. Evidence of Persian's historical influence in the region can be seen in the extent of its influence on the languages of Hindustani (resulting in Urdu), Kashmiri, Punjabi, Sindhi, Gujarati, Bengali and even Telugu, as well as the popularity that Persian literature still enjoys in the region. Persian, the more widely used name of the language in English, is an Anglicized form derived from Latin *Persianus < Latin Persia < Greek ?????? Pérsis, a Hellenized form of Old Persian Parsa. According to the Oxford English Dictionary, the term Persian seems to have been first used in English in the mid-16th century. Native Persian speakers call it "F?rsi" (local name) or Parsi. Farsi is the arabicized form of Parsi, due to a lack of the /p/ phoneme in Standard Arabic. According to Pejman Akbarzadeh, "... In English, however, this language has always been known as "Persian" ('Persane' in French and 'Persisch' in German). But many Persians migrating to the West (particularly to the USA) after the 1979 revolution continued to use 'Farsi' to identify their language in English and the word became commonplace in English-speaking countries." "Farsi" is encountered frequently in the linguistic literature as a name for the language, used both by Iranian and by foreign authors, and is preferred by some.However, The Academy of Persian Language and Literature has declared in an official pronouncement that the name "Persian" is more appropriate, as it has the longer tradition in the western languages and better expresses the role of the language as a mark of cultural and national continuity.
