One doomed to find nothing beside material (4,4)
I believe the answer is:
lame duck
'one doomed to' is the definition.
I can't judge whether this defines the answer.
'nothing beside material' is the wordplay.
'nothing' becomes 'duck' (duck means zero in cricket).
'beside' is a charade indicator (letters next to each other) (I've seen this in other clues).
'material' becomes 'lame' (lame is a kind of material).
'duck' put after 'lame' is 'LAME DUCK'.
'find' acts as a link.
Can you help me to learn more?
(Other definitions for lame duck that I've seen before include "Useless person or thing" , "Person (or bird?) incapacitated by injury etc" , "Person losing power towards the end of a term of office" , "Someone no longer able to perform effectively" , "Ineffectual type" .)
