Hastened end of war with a nuke (3)
I believe the answer is:
ran
'hastened' is the definition.
(I've seen this before)
'end of war with a nuke' is the wordplay.
'end of' suggests the final letters.
'with' says to put letters next to each other.
'nuke' becomes 'n' (this might be a standard abbreviation which I don't know about).
The final letter of 'war' is 'r'.
'r'+'a'+'n'='RAN'
Can you help me to learn more?
(Other definitions for ran that I've seen before include "Hastened" , "Was candidate" , "Managed; raced" , "Took a single" , "Took to one's heels" .)
