Win over the last one listening? (6)
I believe the answer is:
endear
'win over' is the definition.
(I've seen this before)
'the last one listening?' is the wordplay.
'the last' becomes 'end'.
'one listening?' becomes 'ear' (I can't justify this - if you can you should give a lot more credence to this answer).
'end'+'ear'='ENDEAR'
Can you help me to learn more?
(Other definitions for endear that I've seen before include "Arouse affection" , "Attract" , "ingratiate" , "inspire love" , "Make loveable" .)
