Georgian, a Kartvelian language, is actually the official language of Georgia. For all the regional subgroups in Georgia, it's the country's literary language even for the speakers of other Kartvelian languages such as Laz, Svan, and Mingrelian. It doesn't have any grammatical gender, making all the pronouns gender-neutral.
It has a writing system called the Georgian script. And its evolution into a written form resulted from the conversion to Christianity of the country's elite in the fourth century. The new version of the language is based on a well-established cultural structure with appropriate status and functions of the language of pagan Georgia, Aramaic.
