Bets a week's pay about being right (6)
I believe the answer is:
wagers
'bets' is the definition.
('wager' can be a synonym of 'bet')
'a week's pay about being right' is the wordplay.
'a week's pay' becomes 'wages' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'being right' becomes 'r' (common abbreviation).
'wages' placed around 'r' is 'WAGERS'.
(Other definitions for wagers that I've seen before include "Gambles" , "Speculates" , "Bets, stakes" .)
