Play patience (9)
I believe the answer is:
tolerance
This clue is a double definition.
'play' is the first definition.
(thesaurus)
'patience' is the second definition.
(thesaurus)
(Other definitions for tolerance that I've seen before include "Amount of play" , "Indulgence" , "Acceptance - permitted variation in measurement" , "Willingness to accept the beliefs of others" , "Allowable variation (in a dimension)" .)
