Make listener listen finally (4)
I believe the answer is:
earn
'make' is the definition.
('earn' can be a synonym of 'make')
'listener listen finally' is the wordplay.
'listener' becomes 'ear' (I've seen this before).
'finally' indicates one should take the final letters.
The final letter of 'listen' is 'n'.
'ear'+'n'='EARN'
(Other definitions for earn that I've seen before include "Obtain (money) in return for labour or services" , "Make money" , "Gain, take in" , "Deserve; get paid" , "Take home" .)
