Georgia has parking space (3)
I believe the answer is:
gap
'space' is the definition.
(I know that gap is a type of space)
'georgia has parking' is the wordplay.
'georgia' becomes 'GA' (abbreviation for the US state).
'has' means one lot of letters go next to another.
'parking' becomes 'p' (abbreviation on road signs).
'ga'+'p'='GAP'
(Other definitions for gap that I've seen before include "A break or opening as in a hedge" , "fracture" , "Opening, breach" , "Breach or lacuna" , "Break, hole, space" .)
