Say 'Florida', possibly? (5)
I believe the answer is:
state
This clue is a double definition.
'say' is the first definition.
('state' can be a synonym of 'say')
'florida possibly?' is the second definition.
(florida is a kind of state)
(Other definitions for state that I've seen before include "eg Rhode Island" , "Declare: condition" , "Claim" , "A test (anag.)" , "eg Iowa" .)
