Maiden in church to act in affected manner (5)

I believe the answer is:
mince
'act in affected manner' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'maiden in church' is the wordplay.
'maiden' becomes 'm' (cricket abbreviation).
'church' becomes 'ce' (Church of England).
'm'+'in'+'ce'='MINCE'
'to' is the link.
Can you help me to learn more?
(Other definitions for mince that I've seen before include "processed meat?" , "Chop into small pieces" , "Shred (meat)" , "meat that's prepared" , "Ingredient of 8 across" .)
