Don't know these words.

[nìTsìng Lekinama Yayo]

I was reading through the Na'vi ni'aw forum, and I came across a few words that I could find in the dictionary. Help?

The words:
ngian
pameng
pìmeng
tiyevätxaw (I'm pretty sure this is ti<iyev>ätxaw, or was a typo of tì-<iyev>ätxaw. Either way, I don't know what tiätxaw or ätxaw mean.)

Irayo.

[tìngay mungeyu]

Kaltxì!

ngian - however
pameng - p<am>eng - tell (past)
pìmeng - p<ìm>eng - tell (recent past)
tiyevätxaw - t<iyev>ätxaw - return (future subjunctive)

[nìTsìng Lekinama Yayo]

Irayo, Tìngay Mungeyu! 

I can't believe I missed the peng ones. >.> And why I doubled up the i in tiyevätxaw is beyond me. Oe lu skxawng. But at least I'm learning, right?

[tìngay mungeyu]

Nga ke lu skxawng!
We are here to learn and to help each other in learning!

Make sure you have the very latest dictionary. All those words are in there. A lot of words are being added right now, and I seem to recognize one of those as being a very new word.
