Assimilation
Assimilation is a sound change process by which one (neighboring) segment causes another segment to become phonetically more similar to it in some way.
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.
Term properties

Subtypes
Assimilatory changes can be classified according to the following dichotomies:
- partial assimilation vs. total assimilation
- progressive assimilation vs. regressive assimilation
- contact assimilation vs. distant assimilation
