The Tengwar are an artificial script created by J. R. R. Tolkien. Within the fictional context of Tolkien's legendarium, the tengwar were invented by the Elf Fëanor, and used first to write the angelic tongue Valarin and the Elven tongues Quenya and Telerin. Later a great number of languages of Middle-earth were written using the tengwar, including Sindarin. Tolkien used tengwar to write English: most of Tolkien's tengwar samples are actually in English.
