To give a girl fur is a damaging thing to do (7)
I believe the answer is:
disable
'a damaging thing to do' is the definition.
I can't tell whether this defines the answer.
'to give a girl fur' is the wordplay.
'to give' is a charade indicator (letters next to each other).
'a girl' becomes 'Di'.
'fur' becomes 'sable' (sable is a kind of fur).
'di' put next to 'sable' is 'DISABLE'.
'is' is the link.
Can you help me to learn more?
(Other definitions for disable that I've seen before include "Weaken" , "Incapacitate" , "Prevent" , "For hamstring" , "cripple" .)
