History has shaped the words people use every day. Many words in Vietnamese come from Chinese. 
Linguists have studied how the language grew from ancient times. They believe the Austroasiatic language family began spreading around 2000 BC. 
Vietnamese is a major Austroasiatic language. It serves as the official language of Vietnam. Around 86 million people speak it natively. An additional 11 million people use it as a second language. This number is several times larger than the rest of the Austroasiatic family combined.
Structurally, Vietnamese is an isolating language. This means it is highly analytic in its grammar. It is also a tonal language. In tonal languages, pitch changes the meaning of a word. The language has a mix of head-initial and head-final directionalities. Head-initial structures are more common in clauses. Head-final structures appear more often in compounds. Modifiers usually follow the words they modify. However, they sometimes precede them instead. 
Syntactically, Vietnamese is topic-prominent. It follows a strict subject–verb–object order. The language also utilizes noun classifiers to organize words. Most Vietnamese morphemes are monosyllabic. This means they consist of a single syllable. However, multisyllabic words do exist. These usually occur through compounding or reduplication. The vocabulary is also influenced by many external sources. Sino-Vietnamese vocabulary comes from Middle Chinese. French influence also provides many loanwords. 
Writing systems for Vietnamese have evolved significantly. Historically, people used a logographic script called Chu Nom. This script used Chinese characters and local characters. These local characters represented native sounds and words. 

Linguists trace the origins of the language family back to 2000 BC. The arrival of the Phùng Nguyên culture may correspond to the Vietic branch. Ancient Vietic was very different from modern Vietnamese. It was a non-tonal language. It featured sesquisyllabic roots. A sesquisyllabic root has a reduced syllable followed by a full syllable. It also contained many consonant clusters. 
Vietnamese history includes several distinct linguistic stages. Ancient Vietnamese existed before the 10th century. During this time, the language lost voicing distinctions on stop initials. This led to a tone split. Middle Vietnamese lasted from the 16th to the 19th centuries. This period is documented in Jesuit missionary texts.
Sino-Vietnamese vocabulary is a major part of the lexicon. It makes up about one-third of all Vietnamese words. In formal texts, it may account for 60% of the vocabulary. This happened because the Ngô dynasty adopted Classical Chinese. This dominance lasted for many centuries. The language is now a unique blend. It is Austroasiatic at its core. It also carries heavy Sino-influences and French influences.
