As I've been learning Dovahzul, I've been trying to read the various word walls and other scripted text around Skyrim in an effort to improve my understanding of the grammar. I've been referring to the UESP pages for the associated text, and I noticed that the Dragonstone's third line reads [ERei SULeyK SE], and lists the translation as "until power of".

My question is this: why is "se" used instead of "do" in the text? I know "se" is used inside of words to join them but is there another scenario where "se" instead of "do" should be used?

(Here's the link to the page: http://en.uesp.net/wiki/Skyrim:Dragonstone)

Assuming all relevant data are deliberate decisions by Bethesda instead of oversights, there really is no justification besides "that's how it is": se can occur within a word or as a word of its own, while do can only occur as a word of its own.

So it's basically just a matter of what the author wants to write. Alright then, thanks for the explanation!
