This translator will replace English words with Na’vi from James Cameron’s Avatar. However it won’t include the correct grammar. You’ll need to add the relevant prefixes and suffixes to the words to correct the sentences.
The words are from the Na'vi dictionary but some may be missing. Such as there are no articles in Na'vi. ie: (the; a)
If some words are not translating try changing tense to present and use singular instead of plural.

Also note Na’vi has no set word order so the grammar is important.
