IPA: //ʌnˈfeɪθ//
KK: /ʌnˈfeɪθ/
The lack of belief or trust, particularly in a religious context.
His unfaith led him to question the teachings he once followed.
Unfaith → It is formed from "un-" (meaning not) and "faith" (from Old French *feid*, meaning trust or belief). The word "unfaith" means not having faith or trust.
Think of 'not' ('un-') having 'trust' ('faith') — that's why unfaith means lacking trust.
