Serious documentation of the Nyungar language began in 1842 with the publication of A Descriptive Vocabulary of the Language of the Aborigines by George Fletcher Moore, later republished in 1884 as part of Moore's Diary of Ten Years Eventful Life of an Early Settler in Western Australia.
Peter Bindon and Ross Chadwick have compiled an authoritative cross referenced "A Nyoongar Wordlist: from the South West of Western Australia", by assembling material from all of the above writers in their original spelling.
