In which the early bird lies awaiting the worm? (6)
I believe the answer is:
ambush
'in which the early bird lies awaiting the worm?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for ambush that I've seen before include "Wait in hiding to attack" , "Attack from concealed position" , "Launch attack from cover" , "Jump" , "spring a trap" .)
