 Damin is regarded by Lardil-speakers as a separate language and has the only phonological system outside Africa to use click consonants.Lardil is a member of the Tangkic family of Non-Pama–Nyungan Australian languages, along with Kayardild and Yukulta, which are close enough to be mutually intelligible.Though Lardil is not mutually intelligible with either of these, it is likely that many Lardil speakers were historically bilingual in Yangkaal (a close relative of Kayardild), since the Lardil people have long been in contact with the neighboring Yangkaal tribe and trading, marriage and conflict between them seem to have been common.
