Phone city in Alabama (6)
I believe the answer is:
mobile
This clue is a triple definition!
'phone' is the first definition.
(mobile phone)
'city' is the second definition.
(Mobile is an example)
'in alabama' is the third definition.
('Mobile' is part of 'alabama')
(Other definitions for mobile that I've seen before include "Movable, phone say" , "Alabama port; one hung over cot" , "locomotive" , "Means of communicating" , "Able to move freely" .)
