Resents making haste (5)
I believe the answer is:
hates
'resents' is the definition.
The answer and definition can be both to do with human feelings as well as being verbs in their -s form.
Perhaps you can see an association between them that I don't see?
'making haste' is the wordplay.
'making' indicates anagramming the letters.
'haste' is an anagram of 'HATES'.
Can you help me to learn more?
(Other definitions for hates that I've seen before include "Loathes" , "Detests" , "Abhors" , "passionate feelings" , "Dislikes intensely" .)
