Tolerate ill-mannered type (4)
I believe the answer is:
bear
This clue is a double definition.
'tolerate' is the first definition.
(synonyms)
'ill-mannered type' is the second definition.
(Other definitions for bear that I've seen before include "It may be polar or grizzly" , "Press (on) - approach threateningly" , "Go" , "Ursine - carry" , "Carry, convey" .)
