The 'velar nasal' is a type of
consonantal sound, used in some
spoken languages. The symbol in the
International Phonetic Alphabet that represents this sound is , and the equivalent
X-SAMPA symbol is
N.
As a phoneme, the velar nasal does not occur in many of the indigenous languages of the Americas, nor in a large number of European or Middle Eastern languages. While almost all languages have and , only about half have a velar nasal. As with the
voiced velar plosive, the relative rarity of the velar nasal is undoubtedly due to the fact that the small oral cavity used to produce
velar consonants makes it more difficult for voicing to be sustained. It also makes it much more difficult to allow air to escape through the nose as is required for a nasal consonant.
In many languages that do not have the velar nasal as a phoneme, it occurs as an allophone of before velar consonants.
Features
Features of the velar nasal:
★ Its
manner of articulation is
stop, which means it is produced by obstructing airflow in the vocal tract.
★ Its
place of articulation is
velar which means it is articulated with the back part of the
tongue (the dorsum) against the
soft palate (the velum).
★ 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.
The IPA symbol is a lowercase letter ''n'' with a leftward tail protruding from the bottom of the right stem of the letter. Compare n and . Both the symbol and the sound are commonly called as "eng" or "engma" and sometimes in reference to
Greek, "angma". The symbol should not be confused with , the symbol for the
retroflex nasal, which has a ''rightward''-pointing hook extending from the bottom of the ''right stem'' or with , the symbol for the
palatal nasal, which has a ''leftward''-pointing hook extending from the bottom of the ''left stem''.
