The people of Mata Nui had their own language and alphabet.
When liquid protodermis was purified in the Great Temple, a few members of a special group of Matoran read passages in an ancient Matoran dialect asking for the protection and aid of Mata Nui.
Ga-Metru schools taught ancient Matoran dialects, among other things.
Matoran was actually a programming language, unlike Agori.
Matoran was basically a universal language in the universe because they were the most populous intelligent species.
The Matoran language was not English with a few words changed, they had a wholly separate language that was translated in their dialogue and in visual media, save for a few words which remained untranslated.
Vakama uses the word "children" in the epilogue for BIONICLE Adventures #7: Web of the Visorak. This isn't a literal translation of the Matoran word Vakama would have said; the English equivalent to the word he used would likely be closer to "new beings".
There was no connection between the words "Matoro" and "Matoran".
"Mata" was never confirmed to mean "spirit".
"Zamor" possibly meant "sphere", but "Rhotuka" was unlikely to mean "spinner". Its English translation would likely have something to do with the energy coming from inside the user or being unique to them.
"Protodax" probably meant something in the Matoran Language.
The Toa Mata's names were not the Matoran words for their elements.
The Toa Mata's names were based on the elemental prefixes, not the other way around.
"Mahri" likely meant something like "coastline" or "near water" because the village of Mahri Nui was originally built right on the coast.
"Mahri" didn't have an official translation in December 2006, but Greg Farshtey's preference was for it to mean something like "on the coast".
"Kardas" was unlikely to mean "dragon".
In reference to a mask, "Kanohi" always came before the word describing its power.
The official title of a Toa was their Toa Team name followed by their individual name.
Inika meant "energy from a star" and Ignika, one had to assume, meant "life" and it's role was reviving life energy, so it made sense the spellings were similar to each other.

A robber would normally make an effort to slip in and out unnoticed; a Piraka would destroy whatever or whoever was in sight, purely out of spite. Piraka were criminals, looked down upon even by other criminals, as scum. Calling someone by that name had the potential to start a violent, centuries-long feud.
