Word Position For Syntax?

[EywaBlessMe]

If I were to greet some people, I might want to say "Hello, my friends", which would seem to be Kaltxi (hello), oeya (my) ay+'eylan (friends), but I have seen oeya put at the end, so is it "Kaltxi, ayeylan oeya!"?

Word order is not that relevant in leNa'vi.

Kaltxi oeya eylan
Kaltxi eylan oeya
Kaltxi oeya ayeylan
Kaltxi ayeylan oeya

I'd rather not experiment with "Oeya kaltxi ayeylan" as the reciever might understand it as "My thanks you all (???)"

Also why ayeylan ?
That little pause mark ' is removed with lenition (didn't mention it in my lesson, thought it's not that relevant when explaining basics)

Actually, I went to learnnavi, and have read thru all 9 lessons at least once, so I got the jist of lenition.
