Condescend to finish the weeding, possibly (5)
I believe the answer is:
deign
'condescend' is the definition.
(synonyms)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for deign that I've seen before include "Lower oneself" , "Be pleased" , "Condescend; stoop" , "Do something that's below one's dignity" , "Think fit" .)
