Captivate the last listener (6)
I believe the answer is:
endear
'captivate' is the definition.
(I've seen this in another clue)
'last listener' is the wordplay.
'last' becomes 'end' (I've seen this in another clue).
'listener' becomes 'ear' (body part which hears or listens).
'end'+'ear'='ENDEAR'
'the' acts as a link.
(Other definitions for endear that I've seen before include "Evoke love - charm" , "Cause to be beloved" , "inspire love" , "Neared (anag.)" , "Cause to like" .)
