Dish for bad loser in lawsuit? (9)
I believe the answer is:
casserole
'dish' is the definition.
(I've seen this before)
'bad loser in lawsuit?' is the wordplay.
'bad' indicates anagramming the letters.
'in' means one lot of letters goes inside another.
'lawsuit?' becomes 'case' ('case' can be a synonym of 'lawsuit').
'loser' anagrammed gives 'serol'.
'serol' inserted into 'case' is 'CASSEROLE'.
'for' is the link.
(Other definitions for casserole that I've seen before include "(Food cooked in a) stewpot" , "Make a stew" , "Stew; dish" , "Meat dish" , "Dish cooked in an earthenware pot" .)
