Tiipai language

Vowels The Jamul dialect of Tiipai contains seven vowels, four short and three long, as length is contrastive in Tiipai. The only short vowel without a corresponding long vowel is . This phoneme only appears in unstressed positions and is inserted to break up consonant clusters, though its appearance is not entirely predictable. Short vowels in the final position are often followed by aspiration, but unlike other Yuman languages, initial vowels do not have an aspirated onset. Tiipai features many alternations in vowels, with several vowels having multiple allophones. Only predictable variations are discussed below, but there are additional cases where two allophones covary, appearing in the same condition. The phoneme is usually realized as [], though it is realized as between palatals and when stressed and as [] when preceded by or and followed by when stressed. The long vowel // is realized as when stressed and preceding or adjacent to . Additionally, // is realized as when unstressed between and . The vowel is normally realized as [], though it is realized as when stressed and followed by and when unstressed and before . is realized as when stressed and followed by , , or a velar consonant. surfaces as when between palatals (unless it is stressed and preceding ) and when preceded by a consonant other than , , or and followed by . It is realized as before . is consistently realized as between labials. All obstruents in Tiipai are voiceless. The phoneme in Jamul Tiipai is described as apico-dental. Consonants and can be syllabic when in, respectively, a post-stress position following a consonant and in the initial position followed by or and any vowel besides . becomes [] when following a stressed, non-front vowel. In a post-stress position, becomes , while becomes []. In final position, is realized as []. There is one native word, , that contains the voiced bilabial plosive //. Analysis of the term is complicated, so since the phoneme is only found in one native word, is not included in the above table. Both and form diphthongs with all possible preceding stressed vowels, while sometimes forms diphthongs with preceding and in unstressed positions. Stress and syllable structure As is typical of other Yuman languages, Tiipai words contain a singular stressed syllable, always corresponding to the grammatical root. As prefixes vastly outnumber suffixes, stress is usually placed on the final syllable. Syllables are (C)V(C), where the V may be short or long. Biconsonantal clusters are permitted initially, medially, and finally, while triconsonantal clusters are permitted initially and medially. No clusters of a dental and alveolar consonant are permitted and identical consonants cannot form a cluster, with the exception of . Attested final consonant clusters are (with dashes separating phonemes): , , , , , , . Attested vowel clusters include: , , , , , . The glottal stop is only found in stem-initial or root-initial positions, or immediately proceeding a root, where it is followed by a stressed phoneme. The labialized velar consonants are only found syllable-initially in the pre-stress position. Phonological processes Roughly six major rules governing phonemic sound changes have been posited in Tiipai, listed below. Note that deletion may occur in other environments to restore initial and medial clusters, but since this behavior is not fully regular, it is not described as a rule below. • Clusters of glottal stops are reduced: → . • High vowels become glides before and : → , → . • Vowels become shortened when preceding a glottal stop or when pre-stress and not adjacent to the root: → , → . • assimilates to preceding a dental stop: → . • is inserted in a pre-stress position between a non-syllabic segment and a consonant: → . • is deleted in clusters consisting of a sibilant followed by a stop other than or or clusters beginning with the glottal stop: → , → . ==Morphology==

Tiipai employs mostly prefixes, though some suffixes are used frequently. Affixes are almost always a single syllable, and many consist of only a single phoneme. Verbs Verbs bear the majority of morphology in Tiipai, divided between lexical affixes and affixes representing derivational and inflection processes. Lexical affixes Most basic verb stems in Tiipai are made up of the root and one or more lexical affixes. These lexical affixes are not productive, and in many cases their meaning is not clear. However, they are meaningful in the sense that a common semantic notion can be found in a percentage of the verbs that bear the affix, and in many cases the underlying roots never appear without these lexical affixes. However, there are two lexical suffixes that express direction whose meanings are transparent: and . Additionally, lexical reduplication occurs in Tiipai to form verb stems. In 17 instances, full reduplication occurs, with the stress falling on the second syllable: . In five instances, full reduplication occurs except the vowel of the first syllable is reduced to : . Derivational morphology For all derivational processes in Tiipai, there are several morphemes that, unless indicated otherwise, can each independently and optionally express their corresponding morphological function. For example, the causative is formed using any amount of the following affixes, ordered by linear order within the verb: • , , or • Lexical prefix(es) • or • Root (potentially with a change in vowel length) • • As mentioned above, apart from affixes separated by or in the list above, these affixes can co-exist—for example, stative verbs often take , , and : → . Furthermore, some affixes only appear in certain phonological conditions— only appears when the stem ends in a stressed , , or : → . The causative, like other derivational processes, can also cause changes within the stem itself: in 17 cases, lexical affixes are lost, while an intrusive appears in five cases, along with other miscellaneous phenomena. There are two types of plural verbs in Tiipai: plural subject forms, denoting multiple subjects, and distributive action forms, denoting multiple objects. Plural subject forms are formed as follows: • • Lexical prefix(es) • • or • Lexical prefix(es) • • Root (potentially with a change in vowel length) • Lexical suffix, , or • In this derivational process, vowel length change within the root is actually the most productive process, occurring in 72% of stems: → . A few further notes: the position of is not always predictable, frequently occurs with verbs of motion, and and occur only with stems ending in a vowel. Like the causative, loss of lexical affixes and an intrusive may also occur. Distributive action verbs are formed similarly, except the only processes that may occur include prefixation of , suffixation of , and root vowel length change. For distributive action formation, has an allomorph , realized following sibilants: → . Other derivational processes that occur on the verb include: • nominalization on both the subject (referring to a person who habitually or professionally performs the action) and the oblique (referring to a patient, instrument, or location associated with the action) • formation of frequency words • formation of relative stems, or special stems for some verbs when appearing in relative clauses • formation of irrealis stems for some verbs • formation of stative stems for some verbs Inflectional morphology Although a few verbs inflect analytically via an auxiliary, most verbs in Tiipai inflect for person using the following prefixes: • 1st person: '- before stems beginning with a stressed vowel, ∅ elsewhere • 2nd person: • Imperative: • 3rd person: , , or before root initial stems, ∅ elsewhere Special prefixes are used in some combinations when transitive verbs have 1st or 2nd person objects: The "..." indicates intervening lexical prefixes: . Finally, there exist special person prefixes for relative clauses in the subject position: • 1st person: • 2nd person: • 3rd person: ∅ Nouns Albeit much less than verbs, nouns also bear some morphology in Tiipai. Only eight nouns in Tiipai bear plural morphology, and all of these seem to have originated as verbs—this paucity is also likely partly due to the fact that expressing plurality is not even obligatory on verbs. Noun pluralization actually closely resembles the causative, but with only the prefixes and accompanying suffixes and and root vowel length change. The two major instances in which nouns take affixes are possession and case. Possession Tiipai distinguishes two types of possession: inalienable and alienable. Inalienable possession applies to body parts, some items of clothing, , , , and . The following person affixes appear on the possessed nouns: • 1st person: ∅ • 2nd person: • 3rd person: ∅ All other nouns are considered alienably possessed. They inflect similarly, except with the additional prefix appearing after the person affixes: . Case The following markings indicating case are suffixed to the end of the noun phrase: • : subject case • ∅: absolute case • : locative case, realized as the allomorph following a vowel • : instrumental, allative, or comitative case • : ablative or locative case • : inessive or illative case ==Syntax==

The default word order of Tiipai is (S)(O)V. Overt expression of nouns is optional and functions only to specify or "lexicalize", as person for subjects and objects is marked on the verb, as discussed above. If an oblique noun appears, it appears between the subject and the object. For ditransitive verbs, the linear ordering of the two objects is based on an animacy hierarchy: (1st person > 2nd person > 3rd person animate > 3rd person inanimate). This animacy hierarchy also determines which object is marked for person on the verb. Deviations from the default word order are fairly common in discourse. Some attested examples are objects preceding subjects so as to be topicalized and subjects following verbs when they are lexicalized as an "afterthought" to the statement. Noun phrase Lexical demonstratives within Tiipai are typically used for spatial deixis, and they do not inflect for plurality. Three lexical demonstratives are used: , , and . There is also a demonstrative clitic , often used more for textual deixis or marking the ends of complex noun phrases. Multi-word noun phrases are rare, but do occur in certain contexts. A noun followed by the demonstrative is used to specify a referent (), while a genitive construction is ordered with the noun representing the whole followed by the noun representing the part: (car window) . Additionally, in possessive constructions, the owner precedes the possessed noun, which is inflected for alienability and person as discussed above. Case marking The case system of Tiipai is nominative-accusative, although different names have been traditionally used for these cases. Subjects of both transitive and intransitive verbs are marked by the subject case, while objects appear in absolute case. Case marking is obligatory on demonstratives and noun phrases marked with , but is optional elsewhere. Switch reference Tiipai exhibits, like other Yuman languages, a switch-reference system, with different suffixes depending on the mood of the dependent clause. These suffixes are cliticized to the dependent clause verb, and can express simultaneous or sequential events. When the dependent clause is in the realis mood, the suffixes are as follows: • : same-subject • : different-subject • different-subject There are two different-subject suffixes in the realis, but they appear in different contexts. is used for subsequent verbs in switch-reference chains, verbs involving time or weather, and in some auxiliary constructions: {{interlinear|number=(1) {{interlinear|number=(2) is used elsewhere. {{interlinear|number=(3) When the dependent verb is in the irrealis mood, the suffixes are as follows: • : same-subject • different-subject In this case, the reference clause bears the irrealis morphology: {{interlinear|number=(4) For both realis and irrealis moods, in cases of overlapping reference, such as a group as the subject of the first clause and a member of the group as the subject of the second clause, or with weather verbs, either same-subject or different-subject markers may be used. Time verbs, on the other hand, are always different-subject. This phenomenon is typical of other Yuman languages. Furthermore, all switch reference markings are optional. ==References==
