Head going around left piece of crockery (5)
I believe the answer is:
plate
'piece of crockery' is the definition.
(plate is a piece of crockery)
'head going around left' is the wordplay.
'head' becomes 'pate' (humorous term for the head).
'going around' means one lot of letters goes inside another.
'left' becomes 'l' (common abbreviation).
'pate' placed around 'l' is 'PLATE'.
(Other definitions for plate that I've seen before include "Salver" , "Helping of food" , "Thin sheet, as of glass" , "From which food is eaten or served" , "Flat dish for food" .)
