Tenant right beneath Masonic hall (6)
I believe the answer is:
lodger
'tenant' is the definition.
(lodger is a kind of tenant)
'right beneath masonic hall' is the wordplay.
I cannot quite understand how this works, but
'right' could be 'r' (common abbreviation) and 'r' is present in the answer.
'masonic' could be 'lodge' (relating to freemasonry) and 'lodge' is found in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lodger that I've seen before include "Renter of rooms" , "Renter living with owner" , "Long-term paying guest" , "Spare room renter" , "Boarder" .)
