Boy working next to church making pale green porcelain (7)
I believe the answer is:
celadon
'pale green porcelain' is the definition.
The definition suggests a singular noun which matches the answer.
'boy working next to church' is the wordplay.
'boy' becomes 'lad' (informal term for boy).
'working' becomes 'on' (on can mean working or activated).
'next to' says to put letters next to each other.
'church' becomes 'ce' (abbreviation for Church of England).
'lad'+'on'='ladon'
'ladon' after 'ce' is 'CELADON'.
'making' is the link.
Can you help me to learn more?
(Other definitions for celadon that I've seen before include "Greyish-green porcelain" , "Green" , "pottery" .)
