Awkward, fake jewellery? (9)
I believe the answer is:
shambling
'awkward' is the definition.
(shambling can mean clumsy or awkward)
'fake jewellery?' is the wordplay.
'fake' becomes 'sham' (synonyms).
'jewellery?' becomes 'bling' (informal term for jewellery).
'sham'+'bling'='SHAMBLING'
(Other definitions for shambling that I've seen before include "Shuffling along" , "Proceeding inefficiently" .)
