Nasal labio-velar approximant

The nasal labio-velar approximant is a type of consonantal sound used in some oral languages. The symbol in the International Phonetic Alphabet that represents this sound is , that is, a w with a tilde. The equivalent X-SAMPA symbol is w~.

The nasal approximants [ȷ̃] and [w̃] may also be called nasal glides. In some languages like Portuguese, they form a second element of nasal diphthongs.

Transcriptions using may actually intend a non-syllabic vowel, [ũ̯], or, in some dialects of Brazilian Portuguese, a non-syllabic nasalized near-close near-back rounded vowel [ʊ̯̃].
