Accept Kate's different (4)
I believe the answer is:
take
'accept' is the definition.
(taking is a kind of accepting)
'kate's different' is the wordplay.
'different' indicates anagramming the letters.
'kate' with letters rearranged gives 'TAKE'.
(Other definitions for take that I've seen before include "Seize; purloin" , "Accept; (of seed) germinate" , "Remove; capture" , "Money received" , "scene filmed without interruption" .)
