The Georgian script is a graphically independent alphabetic writing system used to write the Georgian language. It is a phonemic orthography and the current alphabet has 33 letters. The Georgian script can also be used to write other Kartvelian languages (Mingrelian, Svan, sometimes Laz), and occasionally other languages of the Caucasus such as Ossetian and Abkhaz during the 1940s. Historically Ingush, Chechen and Avar languages[ were written in the Georgian script, later replaced in the 17th century by Arabic and by the Cyrillic script in modern times. The Georgian word ანბანი (anbani) meaning “alphabet” is derived from the names of the first two letters of the three Georgian alphabets, which, although they look very different from one another, share the same alphabetic order and letter names. The alphabets can be seen mixed in some context, although Georgian is formally unicameral meaning there is normally no distinction between upper and lower case in any of the alphabets.
