Quick answer: “Let someone off the hook” means to release someone from an obligation, blame, or punishment they might otherwise have faced.
Let someone off the hook — To release someone from an obligation, blame, or punishment they might otherwise have faced.
Meaning
When you “let someone off the hook”, you excuse them from a duty, a blame, or a punishment that they would normally have to deal with. The phrase suggests that the person was in a difficult or uncomfortable position — caught, trapped, or expected to answer for something — and is then released from that situation without facing the usual consequences.
The idiom is used across everyday, workplace, and legal-adjacent contexts: a parent might let a child off the hook for a small mistake, a manager might let an employee off the hook for a missed deadline, or a court case might informally be described as letting a defendant off the hook if charges are dropped. It is neutral to informal in register and extremely common in spoken English.
Origin & Usage Note
The idiom likely comes from fishing. A fish that is hooked is trapped and in danger, but one that manages to slip free of the hook escapes that danger entirely. This image of being caught and then released was extended figuratively over time to describe people who escape blame, an unwanted duty, or a punishment. As with many idioms rooted in everyday trades, the exact point at which the phrase moved from literal to figurative use is difficult to pin down with precision, so it is best described simply as a metaphor drawn from angling.
Because the underlying image is so intuitive, the idiom is understood immediately even by learners unfamiliar with its origin. Reference works such as the Cambridge Dictionary list it among common everyday idioms describing escape from responsibility.

How to Use It
The idiom is most often used with the verb “let” plus an object plus “off the hook” (“let him off the hook”), but it can also appear as a state with “be” (“you're off the hook”). It works well in conversation, journalism, and workplace communication. It is not appropriate in strictly formal legal writing, where precise terms such as “acquitted”, “absolved”, or “exempted” would be used instead.
