In J.R.R. Tolkien’s mythology, Fëanor created the Elvish writing system Tengwar.
Tengwar, meaning “letters” in Quenya, is a writing system used for several languages of Middle-earth. Tolkien describes it as a creation of Fëanor, the powerful Noldorin Elf associated with the Silmarils. The system was designed to represent sounds rather than simply copy the shapes of an earlier alphabet.
Tengwar appears in many forms and modes because different languages adapt its letters and vowel marks in different ways. Tolkien used it to write Quenya, Sindarin, English, and other languages in inscriptions and illustrations. The Ring-inscription is one of the best-known examples of Tengwar writing.
Readers sometimes confuse Tengwar with Cirth. Cirth is a separate runic writing system associated especially with the Sindar and later adapted by Dwarves. Celebrimbor is important in the history of the Rings of Power, but Tolkien identifies Fëanor as the inventor of Tengwar.
