How Assimilate Is Used When Speaking of Language Change: Usage Guide

When used as a technical word to describe a certain process of language change, assimilate refers to the habit that some sounds have of becoming more like the sounds that are close to them in a word (see : assimilation). For instance, the original spelling of immovable in English was inmovable, and over time the n began to sound more like its neighboring m, to the point that it actually became that letter. Something similar occurred before assimilate was a word in English. Assimilate comes from the Latin prefix ad- (meaning "to, towards") and similis ("similar"). Over time the d of the prefix ad- assimilated itself with the s of similis.
