Session with nothing for defenceless individual (7,4)
I believe the answer is:
sitting duck
'defenceless individual' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'session with nothing' is the wordplay.
'session' becomes 'sitting' (synonyms).
'with' is a charade indicator (letters next to each other).
'nothing' becomes 'duck' (duck means zero in cricket).
'sitting'+'duck'='SITTING DUCK'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for sitting duck that I've seen before include "Helpless victim" , "Potential victim" , "Wide-open target" , "Obvious target" , "Easy target" .)
