Put up with muddled role in gallery (8)
I believe the answer is:
tolerate
'put up with' is the definition.
('tolerate' can be a synonym of 'put up with')
'muddled role in gallery' is the wordplay.
'muddled' indicates anagramming the letters.
'in' indicates putting letters inside.
'gallery' becomes 'tate' (I've seen this before).
'role' is an anagram of 'oler'.
'oler' placed into 'tate' is 'TOLERATE'.
(Other definitions for tolerate that I've seen before include "Abide" , "Be indulgent" , "Stand" , "Allow" , "Endure, put up with" .)
