Morphology

unfaithful = faithful (transparent) = un + faith + ful

The word is transparently derived from 'faithful' with the prefix 'un-' indicating negation.

Etymology

Unfaithful is made from the prefix un- 'not' and faith 'trust' or 'loyalty', the same root as faithful. So at work, being unfaithful means not staying loyal to your duties or promises.
