A delightful sort of accent (5)

I believe the answer is:

acute

'sort of accent' is the definition.
(I've seen this before)

'a delightful' is the wordplay.
'delightful' becomes 'cute' (I've seen this in other clues).
'a'+'cute'='ACUTE'

(Other definitions for acute that I've seen before include "Extremely sharp or intense" , "Sharp - sort of French accent" , "Sharp or crucial" , "Excruciating" , "Incisive" .)

I've seen this clue in The Telegraph.
