Tolerable – just (4)
I believe the answer is:
fair
I believe this is a double definition.
'tolerable' is the first definition.
(thesaurus)
'just' is the second definition.
(associated in meaning)
(Other definitions for fair that I've seen before include "... enough! - that's reasonable" , "here for the ride?" , "Even-handed travelling show?" , "Pretty good" , "Pretty; impartial" .)
