I'm a little stuck... Click here to teach me more about this clue!

'well-known' is the definition.
(thesaurus)

I cannot understand how the rest of the clue works.

(Other definitions for celebrated that I've seen before include "Notable" , "Did something enjoyable (to mark an event)" , "Publicly honoured" , "Eminent" , "Observed (festival); famous" .)

I've seen this clue in The Globe and Mail and The Guardian.
