The linguolabial nasal is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents it is ⟨n̼⟩ or ⟨m̺⟩.
Features of the linguolabial nasal:
- Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a stop.
- Its place of articulation is linguolabial, which means it is articulated with the tongue against the upper lip.
- 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.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
