Church to copy large one of its subdivisions (6)
I believe the answer is:
chapel
'one of its subdivisions' is the definition.
I can't tell whether this definition defines the answer.
'church to copy large' is the wordplay.
'church' becomes 'ch' (abbreviation on maps etc).
'to copy' becomes 'ape' (ape can mean to copy or imitate).
'large' becomes 'L' (eg in clothes sizes).
'ch'+'ape'+'l'='CHAPEL'
Can you help me to learn more?
(Other definitions for chapel that I've seen before include "service" , "Local printers" , "union group" , "Private church" , "Place of worship with an altar" .)
