Disliked being dispatched into the grass (8)
I believe the answer is:
resented
'disliked' is the definition.
(resenting is a kind of disliking)
'dispatched into the grass' is the wordplay.
'dispatched' becomes 'sent' (I've seen this before).
'into' indicates putting letters inside.
'the grass' becomes 'reed' (I've seen this in other clues).
'sent' placed into 'reed' is 'RESENTED'.
'being' is the link.
(Other definitions for resented that I've seen before include "Considered as an insult" , "Begrudged" , "Felt bitter or indignant about" , "Felt bitterness at (something)" , "Took umbrage" .)
