Grating front bench of office furniture (6,7)
I believe the answer is:
filing cabinet
This might be a double definition.
'grating front bench' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'office furniture' is the second definition.
(filing cabinet is a kind of office furniture)
'of' is the link.
Can you help me to learn more?
(Other definitions for filing cabinet that I've seen before include "Document storage unit" , "Piece of furniture containing documents" , "Item of office furniture" , "Set of drawers for documents" , "where records are kept" .)
