The Svan Alphabet

The Svan alphabet uses 35 characters ^[4] from the Georgian Mkhedruli script: the standard 33 Georgian letters, plus ჷ (Yn, U+10F7) — the schwa vowel /ə/ shared with Megrelian — and ჸ (Elifi, U+10F8) — the glottal stop /ʔ/ unique to Svan.

Both ჷ and ჸ are encoded in the Unicode Georgian block specifically to represent sounds in non-Georgian Kartvelian languages.

Without these two characters, Svan cannot be accurately written in Georgian script.

Svan is the most archaic living Kartvelian language ^[2]. It diverged from Proto-Kartvelian before the split of Georgian and the Zan languages (Megrelian and Laz), meaning Svan has preserved phonological and morphological features that were already lost in the common ancestor of Georgian and Zan.

Svan has: (1) phonemic vowel length — distinguishing long and short vowels; (2) the glottal stop ჸ, a sound reconstructed in Proto-Kartvelian but lost in Georgian, Megrelian, and Laz; (3) complex initial consonant clusters; and (4) a highly complex verb morphology that preserves proto-Kartvelian grammatical categories. ^[1]

The letter ჸ (Elifi) is encoded at Unicode U+10F8 ^[4] in the Georgian block and represents the glottal stop /ʔ/ — the sound heard between the two syllables of the English expression "uh-oh."

In Svan, the glottal stop is a phoneme (a meaning-distinguishing sound), occurring between vowels and in other positions in words. This character was added to Unicode specifically for writing Svan, as no other Georgian-script language regularly uses a glottal stop phoneme.

The Mtavruli capital form Ჸ is encoded at U+1CBF in the Georgian Extended block.

Svan is spoken in the Svaneti region of Georgia ^[1], specifically in Upper Svaneti (Zemo Svaneti) and Lower Svaneti (Kvemo Svaneti) — mountainous districts in the northwestern Georgian highlands. The main Svan-speaking towns are Mestia (capital of Upper Svaneti) and Lentekhi (capital of Lower Svaneti).

Svaneti is one of the most geographically isolated regions in the Caucasus, which has helped Svan preserve its archaic features while surrounding languages evolved.

Due to internal migration, some Svan speakers also live in Tbilisi and other Georgian cities.

Svan is spoken by approximately 30,000–35,000 people ^[1], making it a severely endangered language. All Svan speakers are bilingual in Georgian — Svan is used in family and community contexts, while Georgian is used in education, administration, and public life.

The isolation of Svaneti helped preserve the language historically, but improved transportation and Georgian-medium education have increased language shift to Georgian in recent decades.

Svan is studied as a key resource for reconstructing Proto-Kartvelian, the ancestor of all South Caucasian languages ^[2].

Svan has four main dialects ^[2]: Upper Bal (spoken in the Bal/Bali district of Upper Svaneti), Lower Bal (spoken in lower elevations of the same area), Lashkh (spoken in Lashkheti, part of Lower Svaneti), and Lentekh (spoken in the Lentekhi district of Lower Svaneti).

These dialects differ significantly in phonology — particularly in how proto-Svan vowels developed — and some linguists classify them as separate languages rather than dialects.

The differences between Upper Bal and Lentekh are roughly comparable to the differences between Dutch and German.

Yes — Svan and Georgian are both members of the Kartvelian (South Caucasian) language family ^[1]. However, they are not mutually intelligible — Svan diverged from the Proto-Kartvelian ancestor before Georgian and the Zan languages (Megrelian, Laz) separated from each other.

The relationship is analogous to French and Romanian — both Romance languages, but not mutually intelligible.

Svan preserves many proto-Kartvelian features that were lost in Georgian, which is why Svan is invaluable for comparative Kartvelian linguistics ^[2].

The ISO 639-3 code for Svan is sva ^[3]. Svan does not have an ISO 639-1 two-letter code, which is typical for minority and endangered languages. The Glottolog identifier is svan1243, placing Svan as its own independent branch of the Kartvelian family tree.

In Unicode, Svan-specific characters ჷ (U+10F7) and ჸ (U+10F8) are encoded in the Georgian script block (U+10A0–U+10FF), alongside the standard Georgian letters, reflecting the use of Georgian script as the writing system for Svan.
