We leave the weeding in order to show condescension (5)
I believe the answer is:
deign
'to show condescension' is the definition.
I can't judge whether this definition defines the answer.
'we leave the weeding in order' is the wordplay.
'leave' suggests deleting specific letters.
'in order' indicates an anagram (the letters in a new order).
'weeding' with 'we' taken out is 'eding'.
'eding' is an anagram of 'DEIGN'.
Can you help me to learn more?
(Other definitions for deign that I've seen before include "Think appropriate" , "Do something considered to be below one's dignity" , "Think fit" , "Be pleased" , "Lower oneself" .)
