A saucer from the cupboard (7)
I believe the answer is:
dresser
'cupboard' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for dresser that I've seen before include "What Hardy Amies would do once" , "one coming into line?" , "Actor's costume assistant" , "another" , "Person working in one theatre" .)
