Tengwar is the script J.R.R. Tolkien devised for writing many Elvish languages.
Tolkien’s Tengwar, also known as the Fëanorian characters, is an abjad-like writing system in which consonants are represented by letters and vowels are commonly indicated by marks called tehtar. The system is flexible, so its letters can represent different sounds in different language modes.
In Tolkien’s fictional history, the script was created by Fëanor in the First Age. It spread across Middle-earth and was adapted for languages including Quenya and Sindarin. The form seen in inscriptions and calligraphy can therefore vary according to the language being written.
Tengwar is often confused with Cirth. Cirth is a separate runic writing system associated especially with the Dwarves, although other peoples also used it. Tolkien’s linguistic world includes several scripts because he treated writing as part of cultural history rather than as a single universal alphabet.
