Doubtful, pawnbroker given a ring initially (7)
I believe the answer is:
unclear
'doubtful' is the definition.
(I've seen this before)
'pawnbroker given a ring initially' is the wordplay.
'pawnbroker' becomes 'uncle' (old-fashioned term for a pawnbroker).
'given' is a charade indicator (letters next to each other).
'initially' suggests taking the first letters.
The first letter of 'ring' is 'r'.
'uncle'+'a'+'r'='UNCLEAR'
(Other definitions for unclear that I've seen before include "Not easy to grasp" , "Ill-defined or not easily understood" , "hard to understand" , "in clouds?" , "Imprecise, hazy" .)
