A doctor and I are in Georgia, the country (6)
I believe the answer is:
gambia
'the country' is the definition.
(Gambia is an example)
'a doctor and i are in georgia' is the wordplay.
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus**).
'and' says to put letters next to each other.
'are in' is an insertion indicator.
'georgia' becomes 'ga'.
'a'+'mb'+'i'='ambi'
'ambi' inserted into 'ga' is 'GAMBIA'.
(Other definitions for gambia that I've seen before include "Aim bag toward African state" , "West African river" , "West African country surrounded by Senegal" , "West African country, capital Banjul" .)
