At which one may work or two can play (4)
I believe the answer is:
desk
This might be a double definition.
'at which one may work or two' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'can play' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for desk that I've seen before include "Item of office (or schoolroom) furniture" , "Writing-table" , "Escritoire - service counter" , "Writer's workbench" , "Flat surface for doing paper work" .)
