PS. Late in with the crockery (6)
I believe the answer is:
plates
'ps late in with the crockery' is the definition.
I can't tell whether this definition defines the answer.
'ps late in' is the wordplay.
'in' indicates putting letters inside.
'ps' placed around 'late' is 'PLATES'.
Can you help me to learn more?
(Other definitions for plates that I've seen before include "Strange staple for crockery items" , "Shallow dishes" , "Flat dishes" , "Eating utensils of staple kind" , "Staple for food containers" .)
