A delightful spin which makes a point (5,5)
I believe the answer is:
acute angle
'a point' is the definition.
'a delightful spin' is the wordplay.
'delightful' becomes 'cute' (I've seen this in other clues).
'spin' becomes 'angle'.
'a'+'cute'+'angle'='ACUTE ANGLE'
'which makes' acts as a link.
(Other definitions for acute angle that I've seen before include "That can't be right - it's smaller" , "Meeting point" , "tighter corner" , "That's not right" .)
