Be unable to stand (7)
I believe the answer is:
despise
'be unable to stand' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for despise that I've seen before include "Hate, disdain" , "Loathe, look down on" , "Abhor" , "Feel contempt for (someone/something)" , "Look down upon" .)
