Thinking about minecraft languages again I fear.
We know of at least two diagetic writing systems used in the world of minecraft— enchanting table language and some form of the Roman alphabet. We know that some form of the Roman alphabet is diagetic, because it exists in the world already before the Player arrives. Whoever built the desert temples assigned significance to the letters "TNT" enough to put it on their explosives. Pictographic writing also seems to exist, based on naturally-generating chiseled blocks, but that's harder to definitively state isn't purely decorative.
Villagers also presumably use some form of writing, given that they have librarians, but whatever that writing is, it doesn't seem to be legible to the Player, since we can't read books until we write in them ourselves.
The villager/illager species definitely creates symbolic art, given the use of banners by the illagers and of creeper face symbols on clerical robes. Piglins also use symbolic art, given the snouts carved into bastions, and it seems reasonable to conclude that they have some form of language.
This gives at least three languages in the world of minecraft— Piglin, Villager, and Desert Temple. Possibly a fourth, with Enchanting, but that could just be the writing system used by villagers, given that the Player doesn't seem to be able to read it.
What would those languages be like? What kinds of poetry are written in the Hnnngs and Hrrs of the villagers, or the grunts and snorts of the piglins? Could a piglin and a villager learn each other's languages, or are they too different not just in terms of vocabulary but in terms of the physical features required to communicate? Do piglins carry information in the flapping of their ears? Do villagers produce complex tones by resonance in their large noses?
And what about etymologies? For villagers, wool comes from sheep, but to a piglin, if wool exists at all, it's woven from strider hair. If the inhabitants of the desert temples had a word for gunpowder, was it related to their word for creeper? If piglins do, is it related to their word for ghast?
