King or Queen taking dinner, say, a bit at a time (9)
I believe the answer is:
piecemeal
'a bit at a time' is the definition.
(I've seen this in another clue)
'king or queen taking dinner' is the wordplay.
'king or queen' becomes 'piece' (I've seen this in another clue).
'taking' is a charade indicator (letters next to each other).
'dinner' becomes 'meal' (dinner is a meal).
'piece'+'meal'='PIECEMEAL'
'say' is the link.
(Other definitions for piecemeal that I've seen before include "Gradually, little by little" , "a little at a time" , "step by step" , "Unsystematically" , "A bit at a time" .)
