Wince in embarrassment where church welcomes cartel (6)
I believe the answer is:
cringe
'wince in embarrassment' is the definition.
'cringe' can be an answer for 'wince' (synonyms). I'm not certain of the 'in embarrassment' bit.
'church welcomes cartel' is the wordplay.
'church' becomes 'ce' (abbreviation for Church of England).
'welcomes' means one lot of letters goes inside another (in sense of 'invites in').
'cartel' becomes 'ring' (both can mean a criminal group).
'ce' going around 'ring' is 'CRINGE'.
'where' is the link.
Can you help me to learn more?
(Other definitions for cringe that I've seen before include "Shrink in fear or horror" , "Grovel" , "'Cower, flinch (6)'" , "quail" , "Cower, shrink in fear" .)
