Selections of pieces given to you and me (5)
I believe the answer is:
menus
'selections' is the definition.
The answer and definition can be both related to thinking as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'pieces given to you and me' is the wordplay.
'pieces' becomes 'men' (e.g. in chess).
'given to' says to put letters next to each other.
'you and me' becomes 'us' (the two of us).
'men'+'us'='MENUS'
'of' is the link.
Can you help me to learn more?
(Other definitions for menus that I've seen before include "Bills of fare" , "List of dishes available" , "Restaurant lists" .)
