The earliest examples of the word in print was in a 1919 issue of Smith's Weekly where it was called an ""infernal didjerry" which "produced but one sound - (which sounded like) didjerry, didjerry, didjerry and so on"". It was also used the 1919 "Australian National Dictionary", "The Bulletin" in 1924 and the writings of Herbert Basedow in 1926. There are more than 45 names for this instrument among the Aboriginal people of northern Australia including "Yirdaki". "Yirdaki", also sometimes spelt "yidaki", is for the instrument made and used by the Yolngu people of north-east Arnhem Land.
