Translation attempt

[Tengfya swizaw]

I've been looking at some posts Na'vi nì'aw, and from my several-month hiatus I'm having all kinds of trouble translating them, which is very discouraging.

Ke amomum oel tsat... Srane, tsaw tìngay lu Slä oeyä eltur tìtxen si fì'u

Wouldn't this be something like "I don't know that... Yes, that is the truth, but my brain awakeness and this"
jing tsai, I have so much to catch up on.

Ke <am>omum oe-l tsa-t... Srane, tsaw tìngay lu Slä oe-yä eltu-r tìtxen si fì'u
I didn't know that... Yes, it is true, but to my brain, awakeness is this.

I think that's right, this is as much a learning process to me as it is to you

Almost. The final part, eltur tìtxen si, is a Na'vi idiom meaning that something is interesting.
Also, the middle part, tsaw tìngay lu, actually means "that is the truth", but that's just a minor detail.
Thus, the correct translation is "I didn't know that... Yes, that is the truth, but this is interesting".

Ah, Irayo, that does make much more sense than what the sentence appears to literally mean

[Tengfya swizaw]

That makes sense. Man, I have a lot to catch up on.

I thought that eltur tìtxen si meant Interesting...xD
So with that bit of knowledge, you can say it means "I didn't know that...Yes it is the truth, but it is interesting to me." (Since they used oeyä eltur, it can be said it's interesting to them.)

(Literally the entire thing is ", but this thing awakens my brain.")
