Bar claim in Tennessee (6)
I believe the answer is:
tavern
'bar' is the definition.
(I know that bar can be written as tavern)
'claim in tennessee' is the wordplay.
'claim' becomes 'aver' (I've seen this in another clue).
'in' is an insertion indicator.
'tennessee' becomes 'tn' (I can't justify this - if you can you should believe this answer much more).
'aver' placed inside 'tn' is 'TAVERN'.
Can you help me to learn more?
(Other definitions for tavern that I've seen before include "Watering hole" , "Building with a bar" , "drinking establishment" , "where drink is available" , "An old inn, musically in the town" .)
