When to trot out a childish story (7)
I believe the answer is:
bedtime
'story' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bedtime that I've seen before include "when story comes out?" , "when one's due for retirement?" , "When someone retires" , "The hour for retiring" , "Hour to retire" .)
