That receptive fellow (5)
I believe the answer is:
roger
'fellow' is the definition.
(man's name)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for roger that I've seen before include "Boy's name - message understood" , "One like de Coverley" , "that's clear" , "acknowledgement of message received?" , "Casement, say" .)
