What is the Vietnamese language?

Vietnamese is the native language of the Kinh people, who make up about 90% of Vietnam's population, and serves as the official language of the Socialist Republic of Vietnam. It is also referred to as Kinh language or Việt ngữ and is commonly used as a lingua franca among Vietnam’s ethnic minorities.

While many Southeast Asian languages have been influenced by Indian culture, Vietnam was historically under Chinese rule. As a result, much of its classical literature and historical records were written in Classical Chinese (Hán Văn), making Vietnam a part of the Sinosphere.

In ancient times, Vietnamese was written using Chữ Nôm, a unique script based on Chinese characters, adapted to represent the local language.

However, during the French colonial era, a Romanized script called Quốc Ngữ was developed by French missionaries. This system gradually replaced Chữ Nôm, and in 1945, with the establishment of the Democratic Republic of Vietnam, Quốc Ngữ was officially adopted as the standard writing system for Vietnamese.

Vietnamese Script

Vietnamese uses the Latin alphabet, enhanced with diacritical marks to indicate tones.

However, the letters F, J, W, and Z are generally not used, except in proper nouns and loanwords.

Key Features of the Vietnamese Language

Vietnamese is considered one of the most challenging languages to pronounce in the world. As a tonal language, pronunciation is crucial, featuring six distinct tones that are unfamiliar to Japanese speakers. To speak Vietnamese accurately, one must master 12 monophthongs, 3 diphthongs, 27 initial consonants, and 8 final consonants. The same spelling can have six different pronunciations, each with a unique meaning—mispronouncing a word can lead to confusion or miscommunication. Adding to the complexity, pronunciation varies significantly across Northern, Central, and Southern dialects.

However, Vietnamese grammar is surprisingly simple. Like English, it follows the SVO (Subject-Verb-Object) structure. There are no verb conjugations for tense or person, nor any grammatical changes based on singular or plural forms. Instead, tense and subject distinctions are conveyed through word order and context.

Vietnamese has strong historical ties to the Chinese writing system, much like Japanese. Many commonly used Vietnamese words are of Chinese origin, making them familiar to Japanese speakers. For example:

  • "Chú ý" (チューイー) = 注意 (Attention)
  • "Quản lý" (クアンリー) = 管理 (Management)
  • "Cải cách" (カイカック) = 改革 (Reform)

Recognizing these similarities can make Vietnamese feel more approachable. However, over time, some words have evolved to carry different meanings, so caution is needed when interpreting them.
