Some pans in kitchen may be in this (4)
I believe the answer is:
sink
'be in this' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'some pans in kitchen' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'SINK' can be found hidden inside 'pans in kitchen'.
'may' is the link.
Can you help me to learn more?
(Other definitions for sink that I've seen before include "Submerge; basin" , "Decline - in the kitchen" , "Go down (in the kitchen?)" , "Dig as for well" , "Drop in the ocean?" .)
