Assimilation
PHONOLOGY/PHONETICS: a process in which one or more
segments become adapted in one or more aspects to a
neighbouring segment.
EXAMPLE: in English the
alveolar nasal of the
prefix /in-/ changes to [l] in illegal (complete
convergence) and to [m] in input (partial convergence). In the latter case
the change is from alveolar to labial under influence
of the neighbouring labial segment [p]. When assimilation takes place between two
vowels it is more commonly referred to as vowel harmony.
