How it's used

This idiom carries a strong sense of moral disapproval and is used to describe someone who is fundamentally untrustworthy. It emphasizes the act of repeatedly changing one's stance or breaking promises, making it more descriptive than simply saying someone is a liar. It is often used in arguments or when complaining about someone's lack of integrity.

Examples

Don't go back on your word; you promised to treat me, so don't flake out.
He is always reneging on his promises, who would still believe what he says?

Common phrases

always reneging on one's words

Common mistake

Learners often mistake this for a simple verb, but it functions as an adjective or descriptive phrase. It is not used to describe a single instance of forgetting a promise, but rather a character trait or a pattern of behavior.
