Destroy a one-sided listener with charm (6)
I believe the answer is:
endear
'charm' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for endear that I've seen before include "Draw" , "Cause to be loved" , "Neared in order to charm" , "make sweet" , "Neared (anag.)" .)
