How 17th-century missionaries transformed the Latin alphabet for Vietnam
In short: At first glance, the Vietnamese script looks like a familiar Latin alphabet, but a closer look reveals a complex web of stacked diacritries and tonal marks. This unique system was born from the minds of Portuguese Jesuits, creating a precise tool to capture a language's melodic tones.
The Vietnamese alphabet, known as chữ Quốc ngữ, was originally developed in the early 17th century by Portuguese missionary Francisco de Pina and other Jesuits. While the script is Latin-based, its orthography draws from a diverse linguistic toolkit. The spelling conventions were heavily influenced by Romance languages like Portuguese, Italian, and French, with specific letter combinations like 'gh' and 'gi' borrowed from Italian, and 'c, k, qu' reflecting Latin and Greek origins.
The modern system is remarkably intricate, featuring 29 letters. This includes 22 letters from the ISO basic Latin alphabet and 7 special characters that utilize four distinct diacritics, such as ⟨ă⟩, ⟨â⟩, ⟨ê⟩, and ⟨đ⟩. Beyond these, five additional diacritics are employed to denote the language's various tones, such as in ⟨à⟩ or ⟨ạ⟩. This complexity allows for stacked diacritics on a single letter—for example, in the word 'nhất' (meaning 'first')—making the script easily distinguishable from other Latin-based systems.
The relationship between spelling and sound is a moving target. Because the orthography was established centuries ago, sound changes in spoken Vietnamese have created a disconnect where different letters or digraphs may represent the same sound. For instance, the letters 's' and 'x' can be used interchangeably by some speakers. Furthermore, while the 1984 Ministry of Education attempted to standardize the use of 'i' and 'y', many people and media outlets continue to use the spellings they are most accustomed to, maintaining a vibrant, if non-standard, linguistic tradition.
