Yinwum
Yinwum是帕马-尼荣甘语系的一种语言，过去分布在澳大利亚，现已消亡。
Yinwum is an extinct Paman language formerly spoken on the Cape York Peninsula of Queensland, Australia, by the Yinwum people. It is unknown when it became extinct, but it was no longer spoken by the 1960s. Historically, it underwent some unusual phonological changes that are difficult to classify and understand in phonetic terms.
