About the doctors embracing others in big churches (10)
I believe the answer is:
cathedrals
'churches' is the definition.
(cathedral is a kind of church)
'about the doctors embracing others in big' is the wordplay.
I cannot quite see how this works, but
'about' could be 'ca' (abbreviation for circa) and 'ca' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for cathedrals that I've seen is " religious places".)
