If you say that something rings a bell, you mean that it reminds you of something, but you cannot remember exactly what it is.

For example:

Whenever I see a bee, it rings a bell. I remember when I was stung by one.

Does the name “Fitzpatrick” ring a bell?

No, I’m sorry, that description doesn’t ring any bells with me.

That name rings a bell – I think I’ve met him.

Tradução: me soa familiar, me lembra algo, não me é estranho.
