I propose an alternate meaning.
Karak is pretty straight forward. That's Mountain
Kraka is also straightforward. That's Mountain (In Norse Dwarf).
Ten I have no idea. It's definitely a signifier of some kind. The closest signifier to it in the Khazalid lexicon is -en meaning something is currently taking place, basically present tense. So if we make an assumption, the use of ten is probably to avoid saying Krakaen. There are no words in the lexicon that have those two letters together so it's probably a grammatical rule that ae can't be together in Khazalid.
So literally, it's the Mountaining Mountain. What a great name!
Edit: But seriously though, I have no idea how to make this make sense. Even if -en means something different in the Norse Dawi version of Khazalid, why still use the word Karak in the name? Bah!
So.... The thing about 'Karak' and 'Kraka' is they are assumed to mean Mountain. "Kar" is defined as Big Stone, and ak is "a concept, something abstract such as honour, courage or fortitude", in this case Karak being Mountain, yeah that is a reasonable conclusion. And the assumption with Kraka is it is corrupted Khazalid. Yet, what if Kraka is not corrupted khazalid? 'Kr' does show up in other dwarf words, as said, it comes across as something related to "this person is sick to me". Kr+ak+a = might be Cold Stone + a (of, with, within, to) or it might be Kr+ak+ai which is Kr+ak+ yes, which might be translated as Truly Honestly Really Insanely Freezing Cold Mountain Hold.
"ai" and "a" might be linguistically switchable in writing.
Karak Hirn is known as the Horn Hold.... Karak = Hold, Hirn = Horn, in that translation.
Kron means book.
As for 't' , because en is the suffix, the 't' is part of a word that ends with 't'. Among khazalid those words I found are... Karaggrumbthi = Living Ancestors, krut = a discomforting disease contracted from mountain goats, kruti = a dwrf suffering from krut, krutting = a practise related to goats with a apparently so obvious definiton on what the practise means it does not need to be said. Gronti-Duraz = Rune Golems, Gronti = Giant, Gronit = to do, Gromthi Kron = Book of Ancestors, Gromthi = ancestor, Got = march or travel quickly and with purpose, Git = to go, Girt = broad tunnel with planty of headroom, Ginit = small stone that works its way into your boot causing discomfort, Gatwaz = alley, Okstal = Paid Compensation, Rikkit = a small stone that falls on your head as you walk down a tunnel, Ruebatuki = a term for the clans of the Imperial Dwarfs (I have no idea what ruebatuki means), skrat = to search for gold among rock debris or stream bed/ scavenge/ sparse living, Skrati = poor prospector, Slotch = The sudden mix of water mud and pulverized stone found at the bottom of a mine working, Strataz = street, Werit = a dwarf who has forgotten where he put his tankard of ale, a state of beffudlement, Wut= wood, Wutroth = ironbark, Ziekstik = Goatstaff, Zint = the metal tin,
So, yeah, I chose 'big' because that does seem to be where 't' was being used, both as physically big, and in the metaphorical sense of this is a big deal to a individual.
Ah, well, just fun language things to try and decipher.
Much easier to assume Karak is mountain, and Kraka is mountain. Like Karak Hirn! Montain Horn, nod, nod... hmmmm.
