Recently there's been a lot of discussion about what does oel ngati kameie mean? It's a Na'vi phrase used to greet someone. It's a way of showing that you're acknowledging someone in more ways than just seeing them physically. It's similar to saying hello and also implies respect and understanding. It means you're looking into their soul and their connection to the Pandoran spirit that binds all things, Eywa. This was how Neytiri welcomed Jake when he returned to the Omaticaya clan after he defeated the Toruk beast that had been hunting him.
In the Na'vi language there are transitive and intransitive verbs. Actions like hunting have a target, while actions like waiting do not. This makes it easier to understand what does oel ngati mean when compared with other languages.
