Resistance worker had gin cocktail (6)
I believe the answer is:
gandhi
'resistance worker' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'had gin cocktail' is the wordplay.
'cocktail' indicates an anagram.
'had'+'gin'='hadgin'
'hadgin' with letters rearranged gives 'GANDHI'.
Can you help me to learn more?
(Other definitions for gandhi that I've seen before include "popular leader" , "Indian spinner" , "Follower of one side in the Wars of the Roses" , "Leader who preached non-violence" , "Pacifist Indian leader" .)
