“Listen! Stop supporting a knight around king” (4,2,3)
I believe the answer is:
lend an ear
'listen' is the definition.
(I've seen this before)
'stop supporting a knight around king' is the wordplay.
I cannot quite understand how this works, but
'stop' could be 'end' (synonyms) and 'end' is located in the answer.
'a' could be 'an' and 'an' is found within the answer.
'king' could be 'lear' (King Lear) and 'lear' is found within the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lend an ear that I've seen before include "Hark" , "Pay attention" , "Follow Mark Antony" , "Listen - to borrower" , "Listen attentively (to)" .)
