Tolkien's scripts

[1] The Privata Kodo Skauta (Private Scout Code) from 1909 was designed to be used in his personal diary; it had both an alphabet and some whole-word ideographs.

[2] Late in his life, he created a New English Alphabet structured like Tengwar but written in characters resembling those of Latin and Greek.

[5] Known as the first writing system of Arda, Sarati was invented by the Ñoldorin chronicler Rúmil of Valinor in the Valian Year of 1179.

It was he "who first achieved fitting signs for the recording of speech and song"[6] The writing system is officially called Sarati as each letter of the script represents a "sarat".

[7][8] Within the fictional context of Middle-earth, the Tengwar were invented by the Elf Fëanor, and used first to write the Elven tongues Quenya and Telerin.
