A noisy French one can be delightful (3)

I believe the answer is:

fun

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

'be delightful' is the definition.
(thesaurus)

'a noisy french one' is the wordplay.
'a noisy' becomes 'f'.
'french one' becomes 'un' (I've seen this in other clues. I am not sure about the 'french' bit.**).
'f'+'un'='FUN'

'can' is the link.

Can you help me to learn more?

(Other definitions for fun that I've seen before include "Light-hearted pleasure" , "Entertaining" , "Jollification" , "Enjoyment" , "Light-hearted amusement, jollity" .)

I've seen this clue in the Evening Standard.
