I've been looking into the Matoran dictionary for a while (great job Tolkien!) and I have also made my own list of Kanohi names. When I found this post I was excited! You did a good job Regitnui, but if i could offer a few suggestions: Adaption: Vamutru makes a bit more sense than Vumufu. Vamutru < vamu-mu(t)-ru, from vamu "always changing" and mutru "oriented towards change." Aging: I used a similar translation of "intensive passage of time", but I chose to use Vaduisak < va-duisi-ak, from va "time", duisi "passage", and the intensifying particle -ak. Avaik is good, but doesn't exhibit the actual passing of time (the duisi part). Clairvoyance: I initially went the same way as you did, using ihu "far-seeing" as a base. But "far-seeing" seems to lack the "future" aspect of the mask power. I ended up using Vakama (the future lit: moving time) as a base, and came up with Vakmaku < vakama-aku, from vakama "future", and aku "sight". lit: "future sight". Conjuring: Kamuro < ka-amu-oro, from ka "power", -amu "through, during", and oro "word". lit: "power through word(s)." Elemental Energy: This was was hard. I tried to find a word or phrase that translated directly as "elemental energy" but couldn't (does anyone know of one?). I ended up using Kevua < ke-vua, from ke "restoration" and vua "power reservoir." Its only slightly more descriptive than your Keka. Incomprehension: For this one I used Rau and just took the opposite; Rauku < rau-ku, from rau "understanding" and the negative particle -ku. lit: "non-understanding." Light and Shadow: I thought it would fun to make a name for this one Kavakra. it has two etymologies; 1. kai-avo-kra, from kai "unity", avo "light", and okra "shadow"; "Unity of light and shadow". 2. ka-avak-kra, from ka "power", avak, "bright", and kra "shadow". This last one comes from the supposed paradox of having two opposite powers in one mask; "Bright shadows" cannot exist. Psychometry: you and I almost agreed on this one. I used Lumihi instead of Lumiha. In my case my etymology is lumi-hi, from lumi "insight", and -hi "object". I'm unsure why you used ha instead. Rebounding: I had difficulty with this one as well. I came up with Trakama < ter-kama, from tra variant of ter "guiding force", and kama "to move". lit: "guiding movement". Honestly it sounds too much like an alternate name for a Mataku ("telekinesis"). Scavenging: for this one I had to create a new meaning for the word bour. In the dictionary it is listed as "wilderness, barrenness", but I took it a bit further and translated it as "death", since that is the literal translation of the word; not (plant)-life, not living. my name for this mask is Parzibur < par-zi-bour, from par "strength", zi, "drained, and bur, reduction of bour "death". lit: "strength drained from death." Sensory Aptitude: we completely agree on the naming of this mask; Kamel < ka-mi-el, from ka "power", mi "up, above", and el "detection, sense." lit: "power of increased sense." Good job. Undeath: once I made my new meaning for bour, this mask was easy to name. Urbur < ur-bour, essentially creating a double negative; lit: "not-non-life." This adds to the unnaturalness behind this mask's power. The user is not dead... but not quite alive either. Creation: no list of Kanohi would be complete without this one! For the record, I liked the name you came up with, and I think it sounds cool. If you want an alternate, try this: Takhatra < takha-ter, from take "craft, crafting" and tra variant of ter "guiding force". lit: "guiding force of crafting". I hope this gives you a few more ideas, Regitnui. If you see anything wrong with my translations please tell me (I'm very open to advice). I'm glad someone other than myself took interest in Tolkien's amazing work.
