Damin

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".[3]

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 in a single session, but on the other hand two senior warama men admitted that they lacked a firm command of the register.

Once Damin had been learned, the speakers were known as Demiinkurlda ("Damin possessors"). They spoke the register particularly in ritual contexts, but also in everyday secular life, when foraging, sitting about gossiping, and the like.

The cultural traditions of the Lardil and Yangkaal have been in decline for several decades, and the Lardil and Yangkaal languages are nearly extinct. The last warama ceremony was held in the 1950s, so nowadays Damin is no longer in use by either the Yangkaal or the Lardil.

However, recently a revival of cultural traditions has begun, and luruku has been celebrated. It remains to be seen whether warama ceremonies will also be reactivated.

Damin words had three of Lardil's four pairs of vowels, [a, aː, i, iː, u, uː]; the fourth, [ə, əː], occurred in grammatical suffixes. Vowel length was not contrastive, but depended on the preceding consonant.

Damin was the only click language outside Africa. Damin used only some of the (pulmonic) consonants of everyday Lardil, but they were augmented by four other airstream mechanisms: lingual ingressive (the nasal clicks), glottalic egressive (a velar ejective), pulmonic ingressive (an indrawn lateral fricative), and lingual egressive (a bilabial 'spurt'). Even some of the pulmonic egressive consonants are exotic for the Australian context: fricatives, voiceless nasals, and bilabial trills. The consonants of Damin, in the practical orthography and IPA equivalents, were:[4][lower-alpha 2]

§ These sounds are found in standard Lardil, but not in Damin, apart from grammatical words and suffixes.

L* is described as "ingressive with egressive glottalic release".

There is no alveolar–retroflex distinction in Damin, with the possible exception of the clicks.[lower-alpha 4] However, Hale notes that the Damin alveolar and retroflex clicks (found in the pronouns n!aa, n!uu and in rn!aa, rn!ii respectively) might be in complementary distribution, and it is not clear that they are distinct sounds.

Some of the consonants listed above only occur in clusters. /n̺/ only occurs as a coda. A derivational rule seems to be to pronounce all onset nasals as clicks; it is likely that /ŋ/ is not a click because a velar click in the straightforward sense is not possible.

Damin consonant clusters at the beginning of a word are p'ny [ʘ↑n̠ʲ], p'ng [ʘ↑ŋ], fny [ɸn̠ʲ], fng [ɸŋ], fy [ɸj], prpry [ʙ\ʙj], thrr [t̻ɾ]. Words in normal Lardil may not begin with a cluster. However, Lardil has several clusters in the middle of words, and many of these are not found in Damin words, as Damin only allows n [n̺] and rr [ɾ] in a syllable coda. The attested stem medial Damin clusters are rrd, rrth, rrk, rrb, jb,[5] though j of jb is supposedly not allowed in that position. Other clusters, such as nasal–stop, are produced by Lardil grammatical suffixes.

Hale & Nash posit that Damin syllables (not counting codas) may only be CVV or CCV. Purported CV syllables are restricted to C = [kʼ], [ŋ̊], [ɬ↓ʔ], suggesting that these are underlyingly iterated consonants. Hale suggests they might be k2, ng2, l2 /kk, ŋŋ, ll/ (rather as [ɕ] is a realization of j2 /t̠ʲt̠ʲ/) and also that thrr [t̻ɾ] might be d2 /t̺t̺/. (Note that transcription of vowel length is inconsistent, and the vocabulary given above does not follow these patterns.)

No consonant occurs before all three vowels.[lower-alpha 5] Known sequences are as follows. Note however that with only 150 roots in Damin, and several consonants and consonant clusters attested from only a single root, there are certain to be accidental gaps in this list.

Precede [u] only	p'ng [ʘ↑ŋ], p'ny [ʘ↑n̠ʲ], pr2y [ʙ\ʙj], fng [ɸŋ], fy [ɸj], thrr [t̻ɾ], j2 [t̠ʲt̠ʲ], k' [kʼ], nh!2 [ʇ̃\ʇ̃]
Precede [i] only	fny [ɸn̠ʲ], l* [ɬ↓ʔ], ng* [ŋ̊]
Precede [iː] only	d [t̺], rr [ɾ], y [j], m! [ʘ̃]
Precede [i(ː)] only (not clear if consonant is C or CC)	f [ɸ], pf [ᵖɸ]
Precede [a, u]	n!2 [ʗ̃\ʗ̃]
Precede [aː, uː]	k [k], ng [ŋ], n! [ʗ̃]
Precede [iː, uː]	b [p], th [t̻], j [t̠ʲ], w [w]
Precede [aː, iː]	rn! [ʗ̃˞ ]

/a/ is much less common than /i/ or /u/, the opposite situation from Lardil.
