The invented script associated with the Dwarves in J.R.R. Tolkien’s legendarium is called Cirth.
Cirth consists of angular runes designed for carving into wood, stone, or metal. In Tolkien’s fictional history, the Elves of Beleriand first used the script, but the Dwarves adapted it extensively and developed forms known as the Angerthas. Its appearance reflects the practical demands of inscription rather than the flowing shapes of Tengwar.
Cirth is often mistaken for Tengwar because both are used across Tolkien’s languages and cultures. Tengwar is the more famous Elvish script and appears on the One Ring, whereas Cirth is especially linked with Dwarven writing. Tolkien’s treatment of writing systems shows his interest in how geography, material, language, and cultural history can shape the appearance of letters.
