Dim kinsman after wrappers (7)
I believe the answer is:
unclear
'dim' is the definition.
(thesaurus)
'kinsman after wrappers' is the wordplay.
'kinsman' becomes 'uncle' (uncle is a kind of kinsman).
'wrappers' suggests removing the centre.
'after' with its centre removed is 'ar'.
'uncle'+'ar'='UNCLEAR'
(Other definitions for unclear that I've seen before include "Not definite" , "Vague" , "Doubtful" , "Indistinct" , "Ill-defined or not easily understood" .)
