Drop some plates in kitchen (4)
I believe the answer is:
sink
'drop' is the definition.
(I know that drop can be written as sink)
'some plates in kitchen' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'SINK' is hidden in the letters of 'plates in kitchen'.
(Other definitions for sink that I've seen before include "Plumbing fixture" , "Drop beneath the water - kitchen appliance" , "Get worse" , "Invest capital in - kitchen basin - founder" , "place of iniquity?" .)
