The principal writing system used by the Elves of Middle-earth, devised by Feanor in the Undying Lands and later revised by the Noldorin loremaster Rumil. The Tengwar script is a flowing, elegant system of letters that can be adapted to write different languages, including Quenya, Sindarin, and the Common Speech. The inscription on the One Ring is written in Tengwar characters in the Black Speech of Mordor.
