Ian, bored, that could be carefree (8)
I believe the answer is:
debonair
'carefree' is the definition.
(I've seen this before)
'ian bored that could be' is the wordplay.
'that could be' indicates an anagram.
'ian'+'bored'='ianbored'
'ianbored' with letters rearranged gives 'DEBONAIR'.
(Other definitions for debonair that I've seen before include "Suave and refined" , "Chic" , "Cheerful, lively and self-confident" , "Of good appearance and manners" , "Elegant, jaunty" .)
