Quốc ngữ
Quốc ngữ
The modern Latin-based Vietnamese writing system with diacritical marks, adopted as the national script and used to write all Vietnamese names today.
Quốc ngữ (literally 'national language script') is the Latin-based alphabetic writing system used for modern Vietnamese, including all personal names. Developed by Portuguese and French Jesuit missionaries in the 17th century — most notably Alexandre de Rhodes — Quốc ngữ was gradually adopted as the official script during the French colonial period and became universal after Vietnamese independence.
Impact on Names
The adoption of Quốc ngữ fundamentally changed how Vietnamese names are written and perceived. Before Quốc ngữ, names were recorded in Chinese characters (Hán tự) or Chữ Nôm. Quốc ngữ democratized literacy and made names accessible to all. However, the transition also severed the visible connection between Vietnamese names and their underlying Chinese characters.
Diacritics and Tone Marks
Quốc ngữ uses an extensive system of diacritical marks to represent Vietnamese vowels and tones. In names, these marks are essential — they distinguish entirely different words and meanings. The proper rendering of Quốc ngữ diacritics in names is a matter of identity and respect, though international systems often strip them, creating challenges for Vietnamese people abroad.
