Still short odds (5)
I believe the answer is:
evens
'odds' is the definition.
(I've seen this in other clues)
'still short' is the wordplay.
'still' becomes 'even so' (both can mean 'nonetheless').
'short' means to remove the last letter.
'evenso' with its final letter removed is 'EVENS'.
(Other definitions for evens that I've seen before include "Odds offering equal chance of win or lose" , "Kind of betting odds on seven" , "Fifty-fifty odds" , "less likely than 27 [ODDS-ON]" , "Exchange, substitute" .)
