Nasal palatal approximant
|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.
Transcriptions using 〈j̃〉 may actually intend a non-syllabic nasal vowel, [ĩ̯] (that is, the second element of a diphthong), as in Portuguese, or be ambiguous between the two.
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. However, in some languages (like Swiss German) it can just mean that this consonant is pronounced shorter and weaker than its voiceless counterpart, while its voicedness or lack thereof is not relevant. In such cases it's more accurate to call such sounds lenis or lax.
- 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.
[j̃], written ny, is a common realization of /j/ before nasal vowels in many languages of West Africa which do not have a phonemic distinction between voiced nasal and oral stops, such as Ewe and Bini.
|Portuguese||Brazilian||sonho||[ˈsõj̃ʊ]||'dream'||Allophone of /ɲ/ between vowels, nasalizes the preceding vowel. Language's original /ɲ/ sound. See Portuguese phonology|
|Most dialects||cães||[kɐ̃ĩ̯s]||'dogs'||Non-syllabic allophone of /i/ after nasal vowels, or between nasal occlusives and nasal vowels. Brazilian dialects that have [ɪ] prefer [ɪ̯̃] when in coda position.|
|Some dialects||me ame!||[ˈmj̃ɐ̃mi]||'love me!'|
