Some fellow in sales is successful (4)
I believe the answer is:
wins
'is successful' is the definition.
I can't judge whether this definition defines the answer.
'some fellow in sales' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'WINS' can be found hidden inside 'fellow in sales'.
Can you help me to learn more?
(Other definitions for wins that I've seen before include "Victories" , "Triumphs" , "Finishes in first place" .)
