Keys for the cupboards (7)
I believe the answer is:
lockers
This clue might be a double definition.
'keys' is the first definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe there's an association between them I don't understand?
'cupboards' is the second definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe you can see an association between them that I can't see?
'for the' acts as a link.
Can you help me to learn more?
(Another definition for lockers that I've seen is " Storage compartments for clothes and valuables".)
