Assimilation (phonology)

In phonology, assimilation is a common phonological process by which one sound becomes more like a nearby sound. This can occur either within a word or between words. In rapid speech, for example, "handbag" is often pronounced [ˈhæmbæɡ]. As in this example, sound segments typically assimilate to a following sound (this is called regressive or anticipatory assimilation), but they may also assimilate to a preceding one (progressive assimilation). While assimilation most commonly occurs between immediately adjacent sounds, it may occur between sounds separated by others ("assimilation at a distance").
