Large church making the scholar get attached to a vitreous mineral (8)
I believe the answer is:
basilica
'large church' is the definition.
'attached to a vitreous mineral' is the wordplay.
'attached to' is a charade indicator (letters next to each other).
'vitreous mineral' becomes 'basilic' (I can't explain this - if you can you should give a lot more credence to this answer).
'a' put after 'basilic' is 'BASILICA'.
'making the scholar get' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for basilica that I've seen before include "Bails CIA out of the large church" , "Magnificent church" , "Large (Roman Catholic) church" , "Large church building" , "Romanesque church" .)
