Doze, knocking over cooking vessel (3)
I believe the answer is:
nap
'doze' is the definition.
(thesaurus)
'knocking over cooking vessel' is the wordplay.
'knocking over' says the letters should be written backwards.
'cooking vessel' becomes 'pan' (I've seen this before).
'pan' written backwards gives 'NAP'.
(Other definitions for nap that I've seen before include "Pile (on e.g. velvet)" , "one akin to whist" , "Short sleep on fuzzy fabric surface" , "A brief sleep, forty winks" , "Little sleep" .)
