Has he winning ways? (6)
I believe the answer is:
victor
'has he winning ways?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he winning ways?' is the wordplay.
'he' becomes 'Vic' (short for Victor).
'winning ways?' becomes 'tor' (I am not sure about this - if you are sure you should believe this answer much more).
'vic'+'tor'='VICTOR'
Can you help me to learn more?
(Other definitions for victor that I've seen before include "The . . . . . . comic with Alf Tupper" , "Winner; V (comms)" , "One coming out on top" , "Winning contestant" , "Conqueror" .)
