Na'vi phrase translation help

[JforA]

How would one ask, "Are you silent in the mouth?" in Na'vi?

Thanks again guys for all your help here.

[Vawmataw]

Could you please provide more context so that we can better infer the meaning?

[JforA]

Yes, it's a way of asking if are you unable to speak. I wanted something more poetic though so the question is, are you silent in the mouth.

[Vawmataw]

Yeah, there is no word for mute, only for deaf and blind, so I'm forced to be creative hrh

Ngari kxata aylì'u ke tsun wrrziva'u srak?
The words cannot come out from your mouth?

[Toliman]

Great! I can't find anything as good as this - I'd try: Nga ke plltxe fa aylì'u, srak? (You don't speak by words, isn't it?) But your version is simply better - seykxel sì nitram!
