A monophthong is a "pure" vowel, that stays the same for all of its length.

Monophthongs in English[edit]

Short monophthongs
Long monophthongs
  • /ɔː/ as in "law"
  • /ɑː/ as in "car"
  • /ɜː/ as in "nurse"

Most linguists agree that /iː/ as in "feet" or /uː/ as in "cool" are actually diphthongs, because they do not end with the exactly same vowel as they begin. In the notation of Geoff Lindsey for Southern British English they are [ɪj] and [ʉw].[1]
