Maybe last season (4)
I believe the answer is:
salt
'season' is the definition.
(salting is a kind of seasoning)
'maybe last' is the wordplay.
'maybe' indicates anagramming the letters.
'last' anagrammed gives 'SALT'.
(Other definitions for salt that I've seen before include "Seasoned sailor" , "Sea dog" , "Condiment - experienced sailor" , "Common substance" , "Preserve" .)
