Yabula-Yabula language
Yabula-Yabula in an extinct language of Australia, located in Victoria and New South Wales. Dixon listed it an isolate, but Glottolog evaluates it as a dialect of Yotayota. It shares only 44% of its vocabulary with Yorta Yorta, so is best considered a separate language. This may be due to the rapid lexical change involved after a person's death, as their name then cannot be uttered.
