Help make a wager (4)

Ross

I believe the answer is:

abet

'help' is the definition.
(I've seen this before)

'a wager' is the wordplay.
'wager' becomes 'bet' (synonyms).
'a'+'bet'='ABET'

'make' acts as a link.

(Other definitions for abet that I've seen before include "Aid as in committing crime" , "Incite or encourage" , "Incite (to commit an offence)" , "Help in wrongdoing" , "Egg on" .)

I've seen this clue in The Mirror.
