Adopt a different attitude for rest (6)
I believe the answer is:
repose
'for rest' is the definition.
(synonyms)
'adopt a different attitude' is the wordplay.
I cannot quite understand how this works, but
'attitude' could be 'pose' (attitude can mean a pose or stance) and 'pose' is located in the answer.
The remaining letters 're' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for repose that I've seen before include "calm" , "Relaxation" , "peace" , "Lie at rest" , "place" .)
