Structure of the Vietnamese syllable, diphthongs and triphthongs
Structure of the Vietnamese syllable, diphthongs and triphthongs
The Vietnamese language is strongly organized around the syllable. A simplified working scheme:
onset + medial + nucleus + coda + tone.
Not every syllable contains all components, but the vowel nucleus and tonal characteristic are central.
Nuclear vowel combinations
Three particularly important series:
ia / iê / ya / yê— basic diphthong of the /iə/ type;ua / uô— /uə/ type;ưa / ươ— /ɯə/ type.
The spelling variant depends on the position and the presence of a coda.
Combinations with a final glide
Frequent ones include:
- with a /j/-like ending:
ai,ay,ây,oi,ôi,ơi,ui,ưi; - with a /w/-like ending:
ao,au,âu,eo,êu,iu,ưu.
Triphthongs and complex combinations
Practically important are iêu/yêu, uôi, ươi, ươu, as well as combinations with an initial /w/-like glide: oa, oă, oe, uâ, uê, uy, uyê, etc.
For a learner, it is more useful not to argue about the phonological classification of each combination, but to see three mechanisms:
- internal modification of the nucleus (
iê,uô,ươ); - final glide (
ai,ao, etc.); - initial /w/-like glide (
oa,uy, etc.).
Why this matters for the primer
The alphabet by itself does not teach how to read real syllables. A separate map of how the vowel part is assembled and what codas are permissible is needed.
