Impolitely inquire about ten top ranks in the monastery (6)
I believe the answer is:
priory
'the monastery' is the definition.
(I've seen this before)
'impolitely inquire about' is the wordplay.
'impolitely' becomes 'rio' (I am not sure about this - if you are sure you should believe this answer much more).
'inquire' becomes 'pry' (prying is a kind of inquiring).
'about' means one lot of letters goes inside another.
'rio' inserted into 'pry' is 'PRIORY'.
'ten top ranks in' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for priory that I've seen before include "Religious establishment" , "Religious community" , "where all men are brothers?" , "Small monastery or nunnery" , "Christian religious house subject to an abbey" .)
