To give a girl fur may leave her helpless! (7)
I believe the answer is:
disable
'leave her helpless' is the definition.
I can't judge whether this defines the answer.
'to give a girl fur' is the wordplay.
'to give' means one lot of letters go next to another.
'a girl' becomes 'Di' (short for Diane or Diana).
'fur' becomes 'sable' (sable is a kind of fur).
'di' next to 'sable' is 'DISABLE'.
'may' acts as a link.
Can you help me to learn more?
(Other definitions for disable that I've seen before include "cripple" , "Stop working" , "Deactivate" , "Prevent" , "Put out of action" .)
