Metal objects in water tossed about (7)
I believe the answer is:
tinware
'metal objects' is the definition.
(items made from tin)
'in water tossed about' is the wordplay.
'tossed' indicates anagramming the letters.
'about' indicates putting letters inside.
'water' anagrammed gives 'tware'.
'in' placed inside 'tware' is 'TINWARE'.
(Other definitions for tinware that I've seen before include "Cheap material" , "Articles made of metal plate - wet rain (anag)" , "Metal products" , "can matter?" , "Baking sheets" .)
