Renegements, a rare term, refers to the act of breaking or violating a promise or agreement. Some synonyms for this term include betrayal, treachery, disloyalty, breach, infidelity, deception, falseness, and duplicity. Each word implies a different degree of seriousness in the act of reneging, but all connote a lack of trustworthiness and reliability. Betrayal suggests a particularly severe betrayal of trust, while duplicity implies a double-dealing or deceitful nature. Regardless of the specific word chosen to describe renegement, the core idea remains the same: a failure to fulfill an obligation or agreement, resulting in a breach of trust.
