What people are usually in when they're out? (3)
I believe the answer is:
bed
'out?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bed that I've seen before include "One with flower, sleeper, in" , "Divan" , "Piece of furniture" , "Sleeping place" , "For sleep and flowers" .)
