kepo (no one) no longer valid?

[Lisa]

I was looking at the word list in the conversational vocabulary post http://forum.learnnavi.org/vocab-phrases/conversational-vocab-learn-these-first/ and saw kepo (no one) listed, but it's not in Taronyu's dictionary, the wiki vocabulary or the wikibooks dictionary.  What is listed in all three places is kawtu (no-one, nobody).   I did a LN search for kepo, and nothing showed up, but not even the vocab post showed up, so maybe my search fu is weak.  If this has been covered before, I apologize.

Presumably it existed at one time since it's on the vocab list, but has kepo been banished to the Na'vi lexical graveyard?     

[Taronyu]

Sure looks that way. I've never heard of it, for one, and it's not a Frommerian word as we know it. I'll edit that.

[`Eylan Ayfalulukanä]

I can see how it was derived-- ke(not) po(person). This list is from pretty early on in the history of Na`vi. It could be that someone along the way assembled this word as illustrated above, to fill a need. It got used a few times, and ended up on this (otherwise very useful) list. In any case, Taronyu has already used his magic mod powers to correct this problem.

Irayo, ma Taronyu sì ma `Eylan Ayfalulukanä!

I thought that might be the case as I couldn't find it in the regular resources, but just wanted to make sure. 

['Oma Tirea]

Interesting find.  I wonder then, how come we still have the Frommerian "frapo" instead of something like "fratu"...
