I found something, though took going back to Warcraft III:
Archer: Fandu-dath-belore?
Tyrande Whisperwind: Ishnu-alah, sisters! It is I, Tyrande.
This phrase was also officially translated by Blizzard once:
Darnassian

Usage
Fandu-dath-belore?
Who goes there?
A call to an unknown party for identification.
From this it can be sort of inferred that belore could mean something along the lines of “uncover,” such as in “uncover yourself” to ask for someone to identify themself.
Still looking to see if there’s anything else I can find, though.
I believe it would be largely the same in Darnassian and Thalassian as the only major drift between them seems largely to be grammatical due to how stupidly long elves live.
I can for sure see how a word for revealing/uncovering truth could be extrapolated into having to do with light, and then the sun. Languages are squirrely like that.
I believe this is related to the explanation as to why there would have been Highborne in the ancient empire of nocturnal, night-themed people with the surname, ‘Sunstrider.’ In the case of Dath’remar, his surname would’ve been analogous to, “they whom walk the path of discovery/exploration,” or something.
I suspect that Darnassian is descended from a language equivalent to “Low Elven” in the old Night Elf Empire, a language spoken mainly by tradespeople and the peasantry, where as Thalassian was the language of the Nobility, the cultured version of the same.
In all my play history only ONE NPC ever spoke anything other than Orcish and Common and that was an Auberdine quest giver who gave quests to Night Elves only and spoke in Darnassian. I used to be occasionally by in other characters hearing him speak in Darnassian to Night Elf PCs.
Well, they officially call both Thalassian and Shalassian offshoots of Darnassian… which is a peculiar take but the one they went with. However, it does appear their scripts drifted considerably, if not what they speak.
One thing that came up while digging around is that there are people that have stated that they hear the lines after the second Nordrassil in the music track “Nightsong” that is obviously assosciated with the Night Elves as:
While others hear it as:
I have not found an official sources for the lyrics to “Nightsong” though, so I cannot confirm either way, as sound recognition varies from person to person and is often not something people can agree upon.
No, but there are official translations for some words and phrases.
However, I have yet to find an official source for the meaning of Belore on its own in Darnassian that is written on Wowpedia. Its citation of Golden’s novel is factually incorrect, though.
