An Observation of a certain Rahi's Name
A while ago I found that the Rahi called the Infernavika doesn't really fit into @outofgloom's matoran language, much in the same way Protodermis doesn't fit the Matoran language, so I took it upon myself to create a Matoran appropriate word for the creature.
Tonoris |pn.| lit. "Volcano Bird" [from tono-rīs, tono "volcano, lit. fire-mountain" and rīs from reas "rahi bird"]
Tono |n.| Volcano [from to-ino, tau u-modified tā "spirit/essence, result of process" and ino "mountain, peak". Variant forms: taino, toino"]
This however brought forth an interesting question and conclusion, Infernavika must be Agori, such as how Protodermis must be too, since there is no other place for those words to have come from otherwise.
Breaking it down, Infernavika comes from Inferna-Vika "Pigeon/Bird which Perches near-to/upon Volcanos/Places of Internal Heat." I immediately see a resemblence with Inferna having to be from Ign-Feirna, with Ign coming from Ignis "Fire", which in and of itself coming from the older word/form Signis but thats it's own story to tell. Now what remains is Feirna, and well, it can be broken down further into fei(r)-na, with fei coming from the accusative vowel shifted form of fa into fe "to be bounded with/to, to be with/upon", i "subjunctive/proportional/genitive-collective plural(izer)", and the semantic metathesized na from an "single, individual, one such of (...) who." So ultimately Inferna means "Place of Heat", which may mean any such thing, from a volcano, to a thermal vent, to a furnace or broiler or even to a pot on a lit stovetop or such similar thing, really just a thing which holds heat.
Next is the word Vika which is easier to backtrack, not that the former was difficult however, from Feika, literally "to perch upon, something which perches" so a Pidgeon, within in the confines of it being a bird, with the modern word Vika specifically meaning more or less Pidgeon, along or seperate from the word 'Thunus' which simply means bird in Common Agori, which has variants across the Agori speaking world. Also to note, the skrall word 'veka', which means to settle, comes from a slight semantic shift from feika within the common proto-language of the northern Peshanic Agori, the Svel Peshani "North Mountainers."
