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?
