Largest city in the Bahamas (6)
I believe the answer is:
nassau
'largest city in the bahamas' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nassau that I've seen before include "Caribbean resort" , "city" , "Capital of the Bahamas" , "Port of the Bahamas" , "Bahamas cap." .)
