Cirth [ˈkirθ] was invented by J.R.R. Tolkien for use in his novels. It is modelled on the Anglo-Saxon Runic alphabet, and is used to write the language of the Dwarves (Khuzdul) in The Hobbit and The Lord of the Rings in inscriptions in wood and stone. It is also used as a alternative alphabet for English.
In Tolkein's Middle-earth the Cirth script, or Certhas Daeron, is created by an elf called Daeron, the minstrel of king Thingol of Doriath. It was later expanded and became known as Angerthas Daeron. The Dwarves adopted Cirth to write their language, Khuzdul, as its straight lines were better suited to curving in hard surfaces than the more curved Tengwar letters. Cirth was used by some men and orcs.
