1. Single Vowels (Simple Finals):

These are the basic building blocks, and I've listed them before, but here they are again for completeness:

  • a: father, car
  • o: for, caught
  • e: bed, bet
  • i: see, machine
  • u: moon, flute
  • ü: French "u", German "ü"

2. Compound Vowels (Compound Finals):

These are combinations of two or three single vowels, creating diphthongs and triphthongs:

  • ai: eye, like
    • Example: 爱 (ài) - love
  • ei: eight, grey
    • Example: 杯 (bēi) - cup
  • ao: ow (in cow), loud
    • Example: 好 (hǎo) - good
  • ou: oh (in go), soul
    • Example: 楼 (lóu) - building
  • ia: ya (in yard)
    • Example: 家 (jiā) - home
  • ie: yeah, yes
    • Example: 叶 (yè) - leaf
  • iao: yow (as in "Wow!")
    • Example: 小 (xiǎo) - small
  • iu: yo (as in "yo-yo")
    • Example: 九 (jiǔ) - nine
  • ua: wa (in water)
    • Example: 瓜 (guā) - melon
  • uo: wor (in worm)
    • Example: 国 (guó) - country
  • uai: why
    • Example: 外 (wài) - outside
  • ui: way, sway
    • Example: 回 (huí) - return
  • üe: yue (similar to "ü" with a slight "e" glide)
    • Example: 月 (yuè) - moon
  • iao: yow (as in "Wow!")
    • Example: 鸟 (niǎo) - bird

3. The Special Case of "er":

As we discussed, "er" is a unique syllable that combines a vowel and a retroflex "r" consonant. It's often considered a vowel because it can function as the nucleus of a syllable.

4. Nasal Finals:

Many of the compound vowels can also be combined with nasal endings (-n or -ng), creating even more vowel sounds.

  • an: ahn
    • Example: 安 (ān) - safe
  • en: un (in "sun")
    • Example: 门 (mén) - door
  • in: een (in "seen")
    • Example: 因 (yīn) - because
  • ang: ahng
    • Example: 方 (fāng) - direction
  • eng: ung (in "sung")
    • Example: 灯 (dēng) - lamp
  • ing: ing (in "sing")
    • Example: 听 (tīng) - listen
  • ong: ohng
    • Example: 龙 (lóng) - dragon

Important Considerations:

  • Tones: Remember that each of these vowel sounds can be pronounced with four different tones (plus a neutral tone), which can drastically change the meaning of a word.
  • Regional Variations: There can be variations in how these vowels are pronounced in different regions of China.
