Accept Kate is different (4)
I believe the answer is:
take
'accept' is the definition.
(to accept is to take possession of)
'kate is different' is the wordplay.
'is different' indicates an anagram (letters placed in a different order).
'kate' anagrammed gives 'TAKE'.
(Other definitions for take that I've seen before include "Subtract; assume" , "film sequence" , "Endure; single recording" , "Convey; consume" , "Remove, subtract" .)
