Church with member of flock in charge of pottery (7)
I believe the answer is:
ceramic
'pottery' is the definition.
(I know that pottery can be written as ceramic)
'church with member of flock in charge' is the wordplay.
'church' becomes 'CE' (Church of England).
'with' is a charade indicator (letters next to each other).
'member of flock' becomes 'ram' (male sheep).
'in charge' becomes 'ic' (abbreviation for 'in charge').
'ce'+'ram'+'ic'='CERAMIC'
'of' is the link.
(Other definitions for ceramic that I've seen before include "Like e.g. bowl" , "made of pottery" , "Hard clay" , "potty?" , "Made of clay and hardened by heat" .)
