The 'alveolar nasal' is a type of
consonantal sound used in numerous spoken
languages. The symbol in the
International Phonetic Alphabet that represents
dental,
alveolar, and
postalveolar nasals is , and the equivalent
X-SAMPA symbol is
n.
There are few languages that lack this sound but have an ''m'' sound (e.g., Samoan). There are some languages (e.g., Rotokas) that lack both ''m'' and ''n''.
Features
Features of the alveolar nasal:
★ Its
manner of articulation is
stop, which means it is produced by obstructing airflow in the vocal tract.
★ Its
place of articulation is
alveolar, which means it is articulated with either the tip or the blade of the tongue against the
alveolar ridge, termed respectively ''
apical'' and ''
laminal''.
★ Its
phonation type is voiced, which means the vocal cords are vibrating during the articulation.
★ It is a
nasal consonant, which means air is allowed to escape through the nose.
★ It is a
central consonant, which means it is produced by allowing the airstream to flow over the middle of the tongue, rather than the sides.
★ The
airstream mechanism is
pulmonic egressive, which means it is articulated by pushing air out of the
lungs and through the vocal tract, rather than from the
glottis or the mouth.
