Tengwar is the star-shaped script created by J.R.R. Tolkien for writing many of his Elvish languages.
Tolkien’s fictional writing system is called the Tengwar, a Quenya word commonly translated as “letters.” In Middle-earth, the Elf Fëanor is credited with devising it during the First Age. The script was later adapted for different languages, including Quenya and Sindarin, and could represent sounds rather than being tied to only one spoken language.
The Tengwar consists of distinctive letter forms, or tengwar, arranged according to phonetic relationships. Vowels may be represented by marks called tehtar, depending on the mode used. Tolkien drew and refined examples of the script throughout his life, making it one of his most developed invented writing systems.
Cirth is the main source of confusion: it is a separate runic script associated especially with the dwarves, although other peoples also used it. Sarati was an earlier writing system devised by Tolkien, while Angerthas refers to expanded runic arrangements related to the Cirth.
