The close back unrounded vowel, or high back unrounded vowel,[1] is a type of vowel sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɯ⟩. Typographically a turned letter ⟨m⟩, given its relation to the sound represented by the letter ⟨u⟩ it can be considered a ⟨u⟩ with an extra "bowl".


  • Its vowel height is close, also known as high, which means the tongue is positioned close to the roof of the mouth without creating a constriction that would be classified as a consonant.
  • Its vowel backness is back, which means the tongue is positioned back in the mouth without creating a constriction that would be classified as a consonant. Unrounded back vowels tend to be centralized, which means that often they are in fact near-back.
  • It is unrounded, which means that the lips are not rounded.
