What does "Keelah Si'yah" mean?

Might wanna get a thread about translating all these new Quarian words.

Like Esu se'lai, which probably is something about hoping to see someone in particular. A greeting of someone who isn't looking for a homeworld.

Exactly what I thought Esu se'lai meant.

Sorry to be the bearer of bad news, but while you learned the ways of the Quarian lore, I was molded by it.

Tali says Keelah se'lai, which is the old trilogy greeing, meaning "By the Homeworld I once hope/wish to see." This is how we know Esu se'lai is also a form of greeting.

Since we also know that simply expressing Keelah (which has identical meaning as "My god..." would have for humans, in quite a few sentences) they say "By the Homeworld"

This leaves "se'lai" as the part that says "I once hope/wish to see"

Esu se'lai thus means something along the lines of hoping to see, and considering it's said by Darla vas Hyperion (Yeah, the name was the first thing I noticed, but allow me to shrug at the ambassador retcon), who lived with the Quarians as a kid, as "goodbye" it probably means (as was said) something along the lines "I hope to see you again"


As for Keelah Si'yah, well. We already know the name of the Ark translates as something related to their Homeworld, Rannoch. Someone said that the probable meaning is "By the Homeworld we remember" though exact translation eludes us.

Esu se'lai, Pathfinder.

After the epilogue, the human woman who was raised on the migrant fleet says it when you return to Meridian later and speak to her. That's also when she gives more details about her background. 

I literally rose up in my chair when I heard the "vas Hyperion." Like, "THAT'S A QUARIAN NAME, WHAT IS THE MATTER WITH YOU, EXPLAIN YOURSELF"

The ambassador thing is... I don't know. Did humanity pull the position before Tali's trial? With Shepard invited as her Captain (she did become vas Normandy, after all) it would make sense they would also have a human ambassador there, because suddenly the trial includes a human.

It means "Shameless DLC hook".

Except three hundred years is around the second half of the 19th century, thirty years or thereabouts before we invented aircraft. Humanity found the Relay in 2148 or something.

And no, they talk about the human ambassador to the Migrant Fleet.

We now know what it means, thanks to the book
