Assimilation (linguistics) in the context of "Velar consonant"

Velar consonants 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 (also known as the "velum").

Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsumare not very precise, velars easily undergo assimilation, shifting their articulation back or to the frontdepending on the quality of adjacent vowels. They often become automatically fronted, that is partly or completely palatal before a following front vowel, and retracted, that is partly or completely uvular before back vowels.
