!!!!!!Start by writting everything in backwards and use the preformatting button so the writting reads left to right instead of left to right. (Arabic, Urdu, Farsi; maybe several others; mind yuh's then there is Creole languages and grammar, syntax and so on, etcetera so a mixed syntactic writting between for example: Arabic and English; might include left and right; Izqierda und uhh.. friggin memory? something in espa nola for like, right)
This is one way. There are infinitesmal possabilities to rear extinct languages up; also to "Forge" fakes; Psuedolanguage-ressurections..
Remember that for example the whole "The Dire Wolf is back BS" - Those dire wolves are Genetically modified versions; they are regular wolves today exploited to form a "Dire Wolf"; fine and dandy with me yet the rare genes are all gone. The individuals resemble Dire Wolf yet yes Dire Wolf is related to actual wolves so its similar with language and serves as a exemple or a module or idea.
Another is to write it top to down, use images or other picture formating (Like the extinct Cherokee versions of Seqouya or Chinese Haans (Seqouya's wife thought that Seqouya was practicing witchcraft; literally; and then she burned the life's work of Cherokee or Jalaagi with a Brazilian "Jah"; almost, sorta.. its not pronounced like an English traditional H as in "Wheat Thins" nor Spanish J like "Jalapenño euitsins" one might mispronounce with too much omnomnom while speaking or asking or blabbering here and grabbing more chips there; or vice versa
The language itself can also be transcended into color coding or braiding and twinning of plant fibres such as sweet grass (Hierchloe orodata; which is indeed latin). the syntax may or may not be "Mayan" - City Lights Books sells the only remaining "Mayan" literature
Also there are language youtube videos on languages that resemble "Mayan" linguistics such as Kiche, Aramaya (Bolivian0, and Quechua!
Furthermore bioluminescence such as with Glowing Bitter Oyster and other Fungi, Mycellium, and other Fungu; They all are parts of it. I am nott certain if Indigo was used in older primordial Mayan tying of literary Ropes; the Rope had a loop and several other strands tied and knots woould be for various other parts of the system. Dreamcatchers are similar to that in a certain sense
