Morphology

impaction = impact (transparent) = impact + ion

A direct nominalization of 'impact' referring to a collision or forceful contact; meaning is predictable from the base word.

Etymology

Impaction comes from the word impact, where im- means 'in' and the rest came to mean 'to strike'. So impaction can mean a sharp hit or forceful contact, which is why we use it for a strong collision or the force of a blow.
