Little crash … pot kicked over? (3)
I believe the answer is:
nap
'over?' is the definition.
The answer and definition can be both related to time as well as being singular nouns.
Maybe there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for nap that I've seen before include "Short sleep on soft surface texture?" , "Racing tip that professes to be a certainty" , "Short sleep on fuzzy fabric surface" , "Snatch forty winks" , "Quick sleep; raised pile" .)
