Vietnamese is the official language of Vietnam and is spoken by some 77 million people inside and outside the country, albeit with variations of dialect.
The origin of the Vietnamese language is the subject of debate among linguists, but many considered that it is influenced more by classical Chinese than by any other language.
Vietnamese is one of a few languages in Asia that uses Latin alphabet instead of symbol, which makes it a lot easier to interpret street signs and even to learn to speak. English is the second language, superseding Russian, which was dropped after the USSR collapsed. Some French is spoken, mainly by older people in the south.
