Egg that could go off after a while? (4,4)
I believe the answer is:
time bomb
'egg that could' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'off after a while?' is the wordplay.
'off' becomes 'bomb' (I am not sure about this - if you are sure you should believe this answer much more).
'after' is a charade indicator (letters next to each other).
'a while?' becomes 'time' (I've seen this before).
'bomb' after 'time' is 'TIME-BOMB'.
'go' is the link.
Can you help me to learn more?
(Other definitions for time bomb that I've seen before include "Detonating mechanism with clock" , "a disaster waiting to happen" , "Preprogrammed explosive" , "Scheduled report" , "Delayed explosive" .)
