I’m fascinated by your etymology for Boggarak, and the connection you’ve established between the Visorak and Bohrok. I’ve attempted to derive etymologies for the other Visorak breeds, with varying degrees of success.
Kahgarak: Krana Ca-class, Ga-type
Boggarak: Krana Bo-class, Ga-type
Keelerak: Krana ??-class, Le-type
Oohnorak: Krana Yo-class, Onu-type
Roporak: Krana ??-class, Po-type
Suukorak: Krana Su-class, Ko-type
Vohtarak: Krana Vu-class, Ta-type
I had to stretch a bit to make Oohnorak and Vohtarak work. The latter makes no sense since Visorak don’t fly. I’m completely stumped by Keelerak and Roporak, perhaps we need new headcanon Krana classes. What do you think?
Nice work! This is very similar to the scenarios I've come up with for the Visorak etymologies, with a few tweaks. The first thing to establish is that I didn't try to align the identities of the different Visorak breeds with the actual powers of the Krana markers. Instead, in-universe, I treated this as a case where the Makuta were aware of the Bohrok/Krana and the markers associated with them, but didn't necessarily have access to information about the powers and abilities of the Bohrok/Krana at the time. As a result, here is the breakdown of the Visorak etymologies as I currently have them:
Boggarak = Krana Bo + Ga
Suukorak = Krana Su + Ko
Vohtarak = Krana Vu + Ta
Oohnorak = Krana Yo + Onu
Keelerak = Krana Ca + Le
Roporak = Krana Ja + Po
Kahgarak = Krana Xa ~ Hagah "guardian"
The tricky ones are definitely Oohnorak, Keelerak, and Roporak, as you mention. Oohnorak isn't too hard to fudge with Krana Yo > (y)oh, and Keelerak is similar with Krana Ca > ka > ke(e)-. That leaves Roporak, which I have characterized as aligning with Krana Ja, under the assumption that the <j> is related phonologically to a [g]-like sound in early Matoric, which ends up varying with an [r]-like sound, yield Krana Ja > ra(a) > ro.
