It is primarily spoken within the borders of the Autonomous Republic of Adjara, Georgia, in two villages of the adjacent region of Guria and the ethnic Georgian-inhabited areas of Turkey.
The Adjaran dialect has several subdialects and is spoken with different accents in different locations.
The Upper Adjaran subdialect is found in Khulo and Shuakhevi, and the Lower Adjaran subdialect is found in the Keda, Khelvachauri and Kobuleti regions.
The Upper Adjaran subdialect is similar to Meskhet-Javakhian and resembles Iberian.
The Lower Adjaran subdialect (particularly the Kobuletian-accented version), is similar to western Georgian speech.
