Features

Features of the voiceless labial–retroflex plosive are:

• Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Because the consonant is also nasal, the blocked airflow is redirected through the nose.
• Its place of articulation is labial–retroflex, which means that it is simultaneously articulated with the front part or underside of the tongue against the palate, and the lips.

• Its phonation is un-voiced, which means it is produced without vibrations of the vocal cords.
• It is a nasal consonant, which means air is exclusively allowed to escape through the nose for nasal stops; otherwise, 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.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
