Cirth
The Cirth (Sindarin pronunciation: [ˈkirθ], meaning "runes"; sg. certh [ˈkɛrθ]) is a semi‑artificial script, based on real‑life runic alphabets, one of several scripts invented by J. R. R. Tolkien for the constructed languages he devised and used in his works. Cirth is written with a capital letter when referring to the writing system; the letters themselves can be called cirth.
In the fictional history of Middle-earth, the original Certhas was created by the Sindar (or Grey Elves) for their language, Sindarin. Its extension and elaboration was known as the Angerthas Daeron, as it was attributed to the Sinda Daeron, despite the fact that it was most probably arranged by the Noldor in order to represent the sounds of other languages like Quenya and Telerin.
Although it was later largely replaced by the Tengwar, the Cirth was nonetheless adopted by the Dwarves to write down both their Khuzdul language (Angerthas Moria) and the languages of Men (Angerthas Erebor). The Cirth was also adapted, in its oldest and simplest form, by various races including Men and even Orcs.
Many letters have shapes also found in the historical runic alphabets, but their sound values are only similar in a few of the vowels. Rather, the system of assignment of sound values is much more systematic in the Cirth than in the historical runes (e.g., voiced variants of a voiceless sound are expressed by an additional stroke).
The division between the older Cirth of Daeron and their adaptation by Dwarves and Men has been interpreted as a parallel drawn by Tolkien to the development of the Fuþorc to the Younger Fuþark.[1] The original Elvish Cirth "as supposed products of a superior culture" are focused on logical arrangement and a close connection between form and value whereas the adaptations by mortal races introduced irregularities. Similar to the Germanic tribes who had no written literature and used only simple runes before their conversion to Christianity, the Sindarin Elves of Beleriand with their Cirth were introduced to the more elaborate Tengwar of Fëanor when the Noldorin Elves returned to Middle-earth from the lands of the divine Valar.[2]
In the Appendix E to The Return of the King, Tolkien writes that the Sindar of Beleriand first developed an alphabet for their language some time between the invention of the Tengwar by Fëanor (YT 1250) and the introduction thereof to Middle-earth by the Exiled Noldor at the beginning of the First Age.[3]
