Part of Georgia is actually to the west of here (4)
I believe the answer is:
asia
'here' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'part of georgia is actually to the west' is the wordplay.
'part of' indicates a hidden word.
'to the west' shows that the letters should be reversed in order (letters written right to left or \'east to west\').
'aisa' is hidden in the letters of 'georgia is actually'.
'aisa' in reverse letter order is 'ASIA'.
'of' acts as a link.
(Other definitions for asia that I've seen before include "Continent of the Hindu Kush" , "Continental land mass" , "Great continent" , "huge region" , "Large area" .)
