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⟩.
|Nasal palatal approximant|
The nasal palatal approximant is sometimes called a nasal yod; [j̃] and [w̃] may be called nasal glides.
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, in this case 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.
[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.
