Why did the chicken cross the road? To recover! (3,4)
I believe the answer is:
get over
'to recover' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for get over that I've seen before include "Deal with successfully, improve in health" , "Clear" , "Recover" , "master?" .)
