复韵母Compound Finals
Once you know the six simple finals, this part is mostly assembly: glide from one vowel into the next, or land a nasal tail on it. Six sets, no new sounds to learn from scratch.
Not solid yet on a · o · i · u · ü · e? Warm up with Simple Finals first — everything here just combines those.
Mastering the 6 sets
Each set builds on the simple finals you already know. Tap any set to jump straight to it.
ai · ei · ao · ou
glide straight from the first vowel into the second
an · en · ang · eng · ong
a vowel with a nasal tail — “n” or “ng”
ia · iao · ie · iu · ian · in · iang · ing · iong
built on “i” — nine finals, one starting shape
- With no initial in front, “i” is spelled “y” instead.
- “iu” is short for “iou” — the middle “o” is dropped from the spelling, though a trace of it stays in the sound.
ua · uo · uai · ui · uan · un · uang
built on “u” — seven finals, one starting shape
- With no initial in front, “u” is spelled “w” instead.
- “ui” is short for “uei” — the middle “e” is dropped from the spelling.
- “un” is short for “uen” — the middle “e” is dropped from the spelling.
üe · üan · ün
built on “ü” — the smallest set
- With no initial in front, it’s spelled “yu” instead.
- Combined with j, q, or x, the two dots on “ü” disappear — the sound doesn’t change, the spelling just simplifies.
er
also the erhua suffix — “-r” tacked onto a whole syllable
