When to use 'spill the beans'

Use this idiom when someone accidentally reveals information they were supposed to keep secret. It emphasizes the unintentional nature of the disclosure.

Gold Rule

Avoid in formal contexts

This idiom is informal. In professional or academic writing, use 'reveal,' 'disclose,' or 'let the secret out' instead.
