How do you use hint as a verb?

Excuse me, could you please elaborate on how the word "hint" is used as a verb? I'm trying to understand the various ways in which it can be employed in a sentence. Could you give me a few examples of how one might "hint" at something, and what kind of context it is typically used in? I'm particularly interested in how it differs from other similar verbs like "suggest" or "imply." Thank you for your time and assistance.
