Local mate gets peaceful (4)
I believe the answer is:
calm
'peaceful' is the definition.
(associated in meaning)
'local mate gets' is the wordplay.
'gets' says the answer is hidden in the clue.
'CALM' is hidden in the letters of 'local mate'.
(Other definitions for calm that I've seen before include "Composed or free from storms" , "Peaceful, tranquil" , "Cool, composed" , "Composure or serenity" , "Peaceful, undisturbed" .)
