The Old Permic script (Komi: Важ Перым гижӧм, 𐍮‎𐍐𐍕 𐍟𐍔𐍠𐍨𐍜 𐍒𐍙𐍕𐍞𐍜‎, Važ Perym gižöm), sometimes known by its initial two characters as Abur or Anbur, is a "highly idiosyncratic adaptation"[2] of the Cyrillic script once used to write medieval Komi (a member of the Permic branch of Finno-Ugric languages).

The script derived from Cyrillic and Greek, with Komi "Tamga" signs, the latter being similar in the appearance to runes or siglas poveiras because they were created by incisions rather than by usual writing.

The inclusion of the latter aided the script to greater acceptance among the medieval Permic speakers of the time.

For comparison, an isolated birch bark letter, found in Novgorod and written in Cyrillic in a Finnic language, has been dated to the beginning of the 13th century and Finnish as a written language appeared only after the Reformation in 1543.

Lytkin's 1952 work is often considered the authoritative source of documentation for this script.
