what's the difference between assimilation and elision?
elision is the omission of sounds in connected speech while assimilation is the changing of sounds in connected speech.
elision occurs when a sound which would be present in a word spoken in isolation is omitted in connected speech.assimilation occurs when a phoneme changes its quality to influence a neighbouring sound. such phoneme change to become more like the neighbouring sound or even identical to it.
There are two kinds of elision; the one that results in a loss of syllables and the one that doesn't. The former is called compression and the latter is plainly elision.
There are two kinds of assimilation. when the phoneme that comes first is affected by the one that comes after it, then the assimilation is called regressive. when the phoneme that comes second changes to become like the first phoneme in some way, the the assimilation is called progressive.

what is the difference between coalescent assimilation and regressive and progressive assimilation?
