Charge the earth? (4)
I believe the answer is:
bomb
This could be a double definition.
'charge' is the first definition.
(I've seen this before)
'the earth?' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
Can you help me to learn more?
(Other definitions for bomb that I've seen before include "packet" , "Mine" , "Exploding device" , "Drop" , "Great deal of money (slang)" .)
