Church circle included shrink (6)
I believe the answer is:
cringe
'shrink' is the definition.
(I know that shrink can be written as cringe)
'church circle included' is the wordplay.
'church' becomes 'CE' (abbreviation for Church of England).
'circle' becomes 'ring' (synonyms).
'included' indicates putting letters inside.
'ce' placed around 'ring' is 'CRINGE'.
(Other definitions for cringe that I've seen before include "Shrink away in fear" , "Cower in fear or disgust" , "obeisance" , "Grovel" , "Recoil in embarrassment" .)
