Damin ( in the practical orthography of Lardil) was a ceremonial language register used by the advanced initiated men of the aboriginal Lardil ( in the practical orthography) and Yangkaal peoples of northern Australia. Both inhabit islands in the Gulf of Carpentaria, the Lardil on Mornington Island, the largest island of the Wesley Group, and the Yangkaal on the Forsyth Islands. Their languages belong to the same family, the Tangkic languages. Lardil is the most divergent of the Tangkic languages, while the others are mutually comprehensible with Yangkaal. The Lardil word can be translated as being silent. History Origin The origin of Damin is unclear. The Lardil and the Yangkaal say that Damin was created by a mythological figure in Dreamtime. Hale and colleagues believe that it was invented by Lardil elders; it has several aspects found in language games around the world, such as turning nasal occlusives such as m and n into nasal clicks, doubling consonants, and the like. Evans and colleagues, after studying the mythology of both tribes, speculate that it was the Yangkaal elders who invented Damin and passed it to the Lardil. According to Fleming (2017), "the eccentric features of Damin developed in an emergent and unplanned manner in which conventionalized paralinguistic phonations became semanticized as they were linked up with a signed language employed by first-order male initiates". Past ceremonial use The Lardil had two initiation ceremonies for men, namely luruku, which involved circumcision, and warama, which involved penile subincision. There were no ceremonies for women, although women did play an important role in these ceremonies, especially in the luruku ceremony. It is sometimes said that Damin was a secret language, but this is misleading since there was no attempt to prevent the uninitiated members of the Leerdil tribe from overhearing it. However it was taught during the warama ceremony and, therefore, in isolation from the uninitiated. At least one elder is known, who, though not having been subincised, had an excellent command of Damin, but this seems to have been a unique case. Damin lexical words were organised into semantic fields and shouted out to the initiate in a single session. As each word was announced, a second speaker gave its Lardil equivalent. However, it normally took several sessions before a novice mastered the basics and could use Damin openly in the community. One speaker did claim to have learned to speak Damin
