The largest city in Tennessee (7)
I believe the answer is:
memphis
'the largest city in tennessee' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for memphis that I've seen before include "Largest city in Tennessee" , "Ancient Egyptian city" , "City of Tennessee/Egypt" , "Name of city at different times overlooking the Nile and Mississippi?" , "US city where Gracelands is located" .)
