Some cake for king or queen? (5)
I believe the answer is:
piece
I believe this is a triple definition!
'some cake' is the first definition.
(thesaurus)
'for king' is the second definition.
(thesaurus)
'or' is a link.
'queen?' is the third definition.
(queen is a kind of piece)
(Other definitions for piece that I've seen before include "Segment" , "Scrap - musical work" , "Musical work; bit" , "Portion, bit" , "Portion, coin, item" .)
