After victory, cricketer Marsh almost turns into a salesman (6)
I believe the answer is:
vendor
'marsh almost turns into a salesman' is the definition.
I can't judge whether this definition defines the answer.
'after victory cricketer' is the wordplay.
'after' means one lot of letters go next to another.
'victory' becomes 'v'.
'cricketer' becomes 'endor' (I can't explain this - if you can you should believe this answer much more).
'v' next to 'endor' is 'VENDOR'.
Can you help me to learn more?
(Other definitions for vendor that I've seen before include "A Latin seller" , "Salesperson" , "Person selling" , "who does business?" , "Seller, trader (O, not E)" .)
