morpho-phonological processes involving lenition that occur in the morphological system, such as in allomorphs of the locative case (-goon ~ -yoon ~ -oon). Vowels Bardi has an unusual vowel inventory. It is a seven vowel system, with long and short peripheral (/i/, /a/, and /u/) vowels and /o/, which is short. Short vowels are used much more frequently than long vowels, excepting /o/, the least common vowel quality in Bardi. As expected for languages with rather few vowel qualities, allophonic variation is extensive, though long vowels have a more stable realization. /a/ is probably the most variable vowel, ranging from [æ] to [ɒ], from entirely front to back. /aː/ is more consistently realized as [ɑː]. /i/, /u/, /uː/ are usually a more lower [ɪ] and [ʊ~o(ː)], with /iː/ being closer to the cardinal vowel. Finally, /o/ is most often realized as [ɔ]. While otherwise quite similar to that of languages in the more well-known Pama-Nyungan family, the orthography of Bardi is exceptional in its transcribing of both high-back vowels as 'oo' rather than 'u'. This convention is typical of other Kimberly languages, such as Gooniyandi and Miriwoong. While one might suspect that this orthographic depth could lead to communication difficulties, /uː/ is by far the least common vowel in the language and bears little functional load. Syllable structure Bardi's syllabic template is . Bardi does not allow consonant clusters in the onset, except in borrowed words. A cluster of two consonants is allowed in the coda. That said, "within a syllable coda, the only possibility is /l/, /ɻ/ , or /r/ followed by a nasal which is homorganic with the following stop." Stress Stress is demarcative in Bardi. Primary stress in Bardi is always assigned to the first syllable, and all Bardi words receive this stress. In fact, primary stress even falls on the initial syllable of borrowed words that placed the stress elsewhere in their language of origin. Stress alone never distinguishes between minimal pairs in Bardi. Morphology Bardi is highly affixal, containing both derivational and inflectional affixation. There are four major word classes in Bardi: nominals, verb roots, preverbs, and particles. These classes are defined according to their abilities to combine with other words and to inflect. Regarding their positioning across these two (i.e., distributional and inflectional) measures, "[a]ll four of the primary word classes can be distinguished on distributional criteria and three of the four can be
