Friendly, minutes after fighting (4)
I believe the answer is:
warm
'friendly' is the definition.
('warm' is associated in meaning with 'friendly')
'minutes after fighting' is the wordplay.
'minutes' becomes 'm'.
'after' is a charade indicator (letters next to each other).
'fighting' becomes 'war'.
'm' after 'war' is 'WARM'.
(Other definitions for warm that I've seen before include "(Of a scent) fresh" , "Passionate; ardent" , "Friendly" , "Welcoming - getting close!" , "Neither hot nor cold" .)
