Celebration for nearly everybody in Georgia (4)
I believe the answer is:
gala
'celebration' is the definition.
(I know that celebration can be written as gala)
'nearly everybody in georgia' is the wordplay.
'nearly' means to remove the last letter.
'everybody' becomes 'all' (I've seen this before).
'in' indicates putting letters inside.
'georgia' becomes 'ga' (abbreviation for the US state).
'all' with its final letter taken away is 'al'.
'al' going into 'ga' is 'GALA'.
'for' is the link.
(Other definitions for gala that I've seen before include "Special sports event" , "Social occasion with special performances" , "Public festivity" , "Swimming competition" , "Festive celebration" .)
