Put up with stage's position (10)
I believe the answer is:
standpoint
'position' is the definition.
(standpoint is a kind of position)
'put up with stage's' is the wordplay.
'put up with' becomes 'stand' (both can mean to tolerate or bear).
'stage' becomes 'point' (synonyms).
'stand'+'point'='STANDPOINT'
(Other definitions for standpoint that I've seen before include "Attitude towards a particular issue" , "view" , "Opinion" , "Take" .)
