Resents making haste (5)
I believe the answer is:
hates
'resents' is the definition.
(I've seen this in another clue)
'making haste' is the wordplay.
'making' indicates anagramming the letters.
'haste' with letters rearranged gives 'HATES'.
(Other definitions for hates that I've seen before include "Loathes" , "Detests" , "Abhors" , "passionate feelings" , "Dislikes intensely" .)
