Clear negation of 'faith' in the sense of fidelity or faithfulness; learners who know 'faith' (as faithfulness) and 'un-' will infer 'unfaith' as infidelity.

Etymology

Unfaith joins un- ('not') and faith ('loyal' or 'true'), so it means 'not loyal' to a partner. That's why unfaith can mean cheating in a relationship.
