A nice kind of accent (5)

I believe the answer is:

acute

I believe this clue is a double definition.

'a nice' is the first definition.
(thesaurus)

'kind of accent' is the second definition.

(Other definitions for acute that I've seen before include "Sharp, angle or mind" , "Canny" , "Grave" , "Sharp; type of accent" , "Sharp - sort of French accent" .)

I've seen this clue in The Guardian.
