Where seconds do the work of a minute (6)
I believe the answer is:
corner
This clue could be a double definition.
'where seconds do' is the first definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'work of a minute' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'the' is the link.
Can you help me to learn more?
(Other definitions for corner that I've seen before include "Piece of bacon" , "Where rook is immobilised, initially" , "Monopolise" , "See 11" , "set-piece" .)
