The velar approximant is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɰ⟩. It is the semivocalic counterpart of the close back unrounded vowel
The IPA symbol ⟨ɣ⟩, which otherwise signifies a voiced velar fricative, is more commonly used for the velar approximant than ⟨ɰ⟩ is, with a lowering diacritic ⟨ɣ˕⟩ when specificity is required.
