I hear schedule has Frenchman making comeback (8)
I believe the answer is:
listener
'i hear' is the definition.
(someone who hears things)
'schedule has frenchman making comeback' is the wordplay.
'schedule' becomes 'list' (I've seen this in other clues).
'has' is a charade indicator (letters next to each other).
'frenchman' becomes 'rene' (common French name).
'making comeback' says the letters should be written backwards.
'rene' in reverse letter order is 'ener'.
'list'+'ener'='LISTENER'
(Other definitions for listener that I've seen before include "One lending an ear" , "one should be able to hear it" , "One pays attention in order to hear" , "Puzzle" , "Radio adherent" .)
