Velar consonant
Velars are
consonants articulated with the back part of the tongue (the dorsum)
against the soft palate (the back part of the roof of the mouth, known also as the
velum).
Examples:
- English [g] (as in get or golf), [k] are velar stops
- Scots ch in loch is a velar fricative (SAMPA [x])
- English ng in ring is a velar nasal (SAMPA [N]).
Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum
are not very precise, velars easily undergo
assimilation, shifting their articulation back or to the front
depending on the quality of adjacent vowels.
They often become automatically
fronted, that is partly or completely
palatal before a following
front vowel, and
retracted before back vowels.
Palatalised velars (like English [k] in keen or cube) are sometimes referred to as palatovelars.
Many languages also have labiovelar phonemes, including the approximant [w] and others given symbols like [kw] etc. In these the articulation is accompanied by rounding of the lips.
