Relaxed during conversation (3)
I believe the answer is:
sat
'relaxed' is the definition.
(sitting is a type of relaxing)
'during conversation' is the wordplay.
'during' indicates a hidden word.
'SAT' is hidden in the letters of 'conversation'.
(Other definitions for sat that I've seen before include "Took a seat and posed for a portrait" , "Used a chair" , "Pulled up a 29 down" , "Took a chair" , "Was couch potato" .)
