Claw from rabbit cut leg (5)
I believe the answer is:
talon
'claw' is the definition.
(I know that talon is a type of claw)
'rabbit cut leg' is the wordplay.
I cannot really see how this works, but
'leg' could be 'on' (cricket term, fielding positions) and 'on' is located in the answer.
This explanation may well be incorrect...
'from' acts as a link.
Can you help me to learn more?
(Other definitions for talon that I've seen before include "Claw of a bird of prey" , "Eagle claw" , "Eg, an eagle's claw" , "Part of hobby" , "Hooked claw; cards left after deal" .)
