Nasal palatal approximant

The nasal palatal approximant is a type of consonantal sound used in some oral languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨j̃⟩, that is, a j with a tilde. The equivalent X-SAMPA symbol is j~, and in the Americanist phonetic notation it is ⟨ỹ⟩.

The nasal palatal approximant is sometimes called a nasal yod; [j̃] and [w̃] may be called nasal glides.

Features

Features of the nasal palatal approximant:

  • Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream.
  • Its place of articulation is palatal, which means it is articulated with the middle or back part of the tongue raised to the hard palate.
  • Its phonation is voiced, which means the vocal cords vibrate during the articulation.
  • It is a nasal consonant, which means air is allowed to escape through the nose, either exclusively (nasal stops) or in addition to through the mouth.
  • It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
  • The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.

    • Occurrence

    [j̃], written ny, is a common realization of /j/ before nasal vowels in many languages of West Africa that do not have a phonemic distinction between voiced nasal and oral stops, such as Ewe and Bini.
