Linguistic assimilation?

There are a handful of words in English that are examples of themselves, representatives of the very things that they describe. One such word is sesquipedalian ("having many syllables" or "characterized by the use of long words"). Another example, in a slightly less obvious fashion, is assimilate. 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, sense 3). 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.
