Likeable wannabe's edging into group (5)
I believe the answer is:
sweet
'likeable' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
'wannabe's edging into group' is the wordplay.
'edging' suggests removing the centre (edging means the letters on the edges).
'into' means one lot of letters goes inside another.
'group' becomes 'set' (both can mean a collection).
'wannabe' with its middle removed is 'we'.
'we' inserted inside 'set' is 'SWEET'.
Can you help me to learn more?
(Other definitions for sweet that I've seen before include "bon-bon" , "attractive" , "Cute" , "darling" , "S [SWEET] , basically" .)
