Fellow, guy (4)
I believe the answer is:
chap
I believe this is a double definition.
'fellow' is the first definition.
(both can mean a man)
'guy' is the second definition.
(both can mean a man)
(Other definitions for chap that I've seen before include "Fellow < makes > crack" , "Bloke, fellow" , "Fellow; sore skin area" , "Cracked patch (of skin) - gentleman" , "Become sore; fellow" .)
