J.R.R. Tolkien named his fictional writing system Tengwar.
Tengwar is a script used in Tolkien’s invented world to write several languages, including Quenya and Sindarin. The word comes from Quenya and means “letters” or “signs.” Tolkien designed the script with distinct letter forms and a system in which consonants are represented by signs while vowel marks are placed around them.
Tengwar is not itself a language; it is a writing system. This distinction is a common source of confusion. Tolkien also created Cirth, an angular runic script associated especially with dwarves and other peoples. The famous inscription on the One Ring is written in Tengwar script, but its language is the Black Speech of Mordor.
