Reykunyu ("someone who lets you discover things") is a dictionary in which you can search for Na'vi words and see the English translation and other information about that word. Reykunyu tries to give more detailed information than other dictionaries. The Naʼvi language is a fictional constructed language originally made for the 2009 film Avatar. In the film franchise, the language is spoken by the Naʼvi, a race of sapient humanoids indigenous to the extraterrestrial moon Pandora.
