Effect a cure for the bottom of the leg, I say (4)
I believe the answer is:
heal
'effect a cure' is the definition.
(I've seen this in another clue)
'bottom of the leg i say' is the wordplay.
I cannot quite see how this works, but
'i' could be 'a' and 'a' is found within the answer.
The remaining letters 'hel' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'for the' is the link.
Can you help me to learn more?
(Other definitions for heal that I've seen before include "Cure, recover" , "Restore to health" , "Cure, mend" , "Cure, restore" , "Cure, make well" .)
