Spatial deixis and demonstratives in the Kirati languages

This paper delves into the spatial deixis (deictic) embedded in the Kirati languages namely Bantawa, Bayung, Chamling, Dumi, Dungmali, Koyee, Khaling, Kulung, Limbu, Lohorung, Nachhiring, Puma, Sampang, Thulung, Wambule and Yamphu within the comparative and cross-linguistic context. The data drawn in this paper were collected from the direct elicitation from the speakers of more than a dozen Kirati languages. The findings of this study reveal that the Kirati languages share the spatial deictic features almost in the same pattern. The Kirati languages exhibit the locative suffixes for 'above, up', 'below, down' and 'across' indicating by various deictic suffixes. Vertical deictic like 'up here', 'down here' and 'over here' are realized in different ways in terms of the deictic suffixes. It is interesting that all the Kirati languages are not treated in the same way in both of the vertical deixis, i.e. Bantawa, Dungmali and Wambule have the same lexicon to denote 'above' and 'over'. But the other languages discussed in this article are treated in both of the paradigms. The deictic roots are also nominalized with suffixes in the Kirati languages. Typologically, Dungmali, Bantawa, Thulung, and Puma might be grouped into one whereas the languages like Yamphu, Koyee, Khaling, Dumi and Lohorung may be grouped into another category. There are some other Tibeto-Burman languages like Gurung, Tamang and Manangba that may be grouped into third category the way they are treated with the locational suffixes. The rest of the languages share the individual locational markers.

Waning and waxing

Abstract This paper provides a preliminary description of the comparative construction in Tujia1 (northern dialect; NT), an endangered ergative Tibeto-Burman (TB) language spoken in China, in the context of the typologically diverse ways in which comparative meaning is expressed. In mono-clauses in NT, comparative marking depends on the position of the standard (i.e., that which is compared to). The standard may be marked with an ablative marker, or a topic marker if it appears in sentence-initial position due to left dislocation; otherwise, the comparandum (i.e., that which is to be compared) is assigned an ergative marker. Ergative on the comparandum and ablative on the standard can both occur but this is not obligatory. We propose that the ablative is the primary comparative marker in NT. However, this construction is subject to variation: the ablative marker is being replaced by a topic marker on the standard or by an ergative marker on the comparandum. We analyze this as change in progress (partly as a result of language contact); specifically, we propose that an ergative marker on the comparandum is starting to function as a focus marker, and in which the comparative meaning is derived from reanalysis. On the other hand, the comparative meaning in constructions where the standard is marked with a topic marker is proposed to result from the functional extension of the topic structure to comparative constructions. Both ergative marking on the comparandum and topic marking on the standard are typologically rare. Thus, the analysis of comparison marking in Tujia contributes to the typological understanding of comparative constructions in general.

The multiple functions of the reflexive pronoun in Tujia

Abstract This paper investigates the functions of the reflexive pronoun ko 53 to 21/to 21 in Tujia, a Tibeto-Burman (TB) language. Apart from being used as a verb object, the reflexive pronoun in Tujia can be used as an intensifier, indicating “self, non-other”, but it can also be used to create “passive” or “causative” meaning. It is argued that both meanings created by the reflexive pronoun can be accounted for under a decomposition approach. Verbal reflexives isomorphic with anti-causative or passive morphemes have been reported for European languages, while a reflexive pronoun with causative meaning is quite rare. The present paper therefore contributes not only to the typology in this area but also to the expression of causative and passive in Tibeto-Burman languages.

Tone sandhi in Nuosu Yi at the interface

Abstract Nuosu Yi, a Tibeto-Burman language, has a tone sandhi pattern, where a lexical [33] -tone is realized as [44]-tone on the surface. This tone sandhi pattern in Nuosu Yi is described as having a “weak phonological status (Gerner, 2013: 28)”. In this study, we confirm this observation and further show the role of phonological length in the tone sandhi patterns. A closer examination of the sandhi contexts, however, reveals an intricate interplay between phonology and morphology of various aspects of Nuosu Yi grammar. Tone sandhi is conditioned by word size and morphological processes. Monosyllabic words, but not multi-syllabic words, tend to undergo tone sandhi, and tone sandhi is sensitive to morphological operations such as compounding.

“Come thou the spirits of village and locality, come thou the spirits of sons and daughters!”

Abstract This paper discusses the ritual language of Thadou-Kuki, a Tibeto-Burman language of the Kuki-Chin subgroup spoken in Northeastern India and the Chin State of Myanmar. The paper examines 13 ritual texts to determine the nature of language use and the types of structure that ritual language provides. The paper discusses the general belief surrounding the traditional religion as background information to the types of ritual language discussed in the paper. This is followed by a discussion on the structure of ritual language in terms of composition, grammatical constructions, and the choices of words used in the ritual language of Thadou-Kuki, including archaic expressions that are characteristic of ritual language. From the analysis of the ritual texts, the paper discusses the types of repetition at the level of syllables and paragraphs/stanzas. Each stanza is further divided into couplets of repetitive phrases (differing mostly in the initial words of a phrase or sentence). The paper divides the ritual language of Thadou-Kuki into two, namely invocation and direct address to the spirits. The former makes use of imperatives, namely the request –ô, the invitational –în, and the hortative –hèen. Direct address to the spirits, on the other hand, makes use of the declarative mood, namely, a clause or sentence-final marker –e.

Multi-class identification of tonal contrasts in Chokri using supervised machine learning algorithms

This study examines and explores the effectiveness of various Machine Learning Algorithms (MLAs) in identifying intricate tonal contrasts in Chokri (ISO 639-3), an under-documented and endangered Tibeto-Burman language of the Sino-Tibetan language family spoken in Nagaland, India. Seven different supervised MLAs, viz., [Logistic Regression (LR), Decision Tree (DT), Random Forest (RF), Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Naive Bayes (NB)], and one neural network (NN)-based algorithms [Artificial Neural Network (ANN)] are implemented to explore five-way tonal contrasts in Chokri. Acoustic correlates of tonal contrasts, encompassing fundamental frequency fluctuations, viz., f0 height and f0 direction, are examined. Contrary to the prevailing notion of NN supremacy, this study underscores the impressive accuracy achieved by the RF. Additionally, it reveals that combining f0 height and directionality enhances tonal contrast recognition for female speakers, while f0 directionality alone suffices for male speakers. The findings demonstrate MLAs’ potential to attain accuracy rates of 84–87% for females and 95–97% for males, showcasing their applicability in deciphering the intricate tonal systems of Chokri. The proposed methodology can be extended to predict multi-class problems in diverse fields such as image processing, speech classification, medical diagnosis, computer vision, and social network analysis.

Tense and Aspect in Balti Language: Morphological Perspective

Pakistan is a multilingual and multicultural country where 72 language diverse languages are used for communication. Gilgit-Baltistan is one of the most well-known northern regions for its stunning natural beauty, distinct landscapes, evergreen forests, snow-capped mountains, and rich cultural heritage. Most of the Gilgit-Baltistan regional languages have been studied historically and culturally, but a few studies address this from a linguistic perspective. Balti language is one of them. Balti is a member of the more extraordinary Tibeto-Burman language family, specifically the Western Tibetan branch of the Tibetan language family. The present study analyses the tense and aspect markers in the Balti language. This study contributes to the regional language of Pakistan and analyzes the language in the morphological domain that is not mostly touched yet; also, studying tense and aspect markers in the Balti language from a morphological perspective is crucial for understanding the language’s nuances within temporal expressions. The present study results show that Balti has a complex system of tense and aspect markers; using the qualitative research design, n= 50 root words (verbs) were collected from the Balti language within the framework of inflectional morphemes of tense markers for this study. Nine markers for tense and some of their aspect, including eḑ, en, s, yoḑ, and yoḑpə: set̪, ʊk, t̪ʊk, and sed̪ʊkt̪ʊk, are identified in the current study. These markers are attached to the corresponding root verbs to indicate the present simple, present progressive, past simple with progressive, future simple, and future participle. The study also develops a deep understanding of various future tense markers as connectors to root words based on the consonant and vowel sounds at the end of root words.

The role of place and manner of articulation in Kurtöp tonogenesis: refining the model.

While the general acoustic mechanisms that explain the development of tone in language have been understood since at least Maspero (1912. Étude Sur La Phonétique Historique de La Langue Annamite: Les Initiales. Bulletin de l'École Française d'Extrême-Orient 12. 1-126), we are still far from having a predictive theory of tonogenesis. Kurtöp, a Tibeto-Burman language of Bhutan shown to be undergoing tonogenesis, provides a rare opportunity to advance our understanding of how and why languages develop lexical tone. This study examines the role that sonority and place of articulation have in the spread of tone from voicing contrasts on preceding consonants in Kurtöp. First, we find that tone is more likely to be produced following fricatives than when following stops. Second, we see that within the stops, tone phonologises more readily following some places of articulation over others. Taken as a whole, this shows us that tone is moving through Kurtöp, following the most sonorous segments first and moving to the least sonorous segments. These findings thus help us refine our theory of tonogenesis and show that functional pressures have strong influences in this particular pathway of sound change.

Tense and Lax Vowels in the Lahu Dialect of Yunshan: A Laboratory Phonological Study

A controversy exists regarding whether there are tense-lax vowels in Lahu and whether tense-lax phonation should be accorded phonological status, an issue that is closely related to the physiological movement of the larynx. This study presents an experimental analysis of the acoustic features of the Lahu dialect of Yunshan, using electroglottography to collect acoustic and physiological data and employing VoiceSauce and Eggworks to extract glottal features to explore laryngeal mode of motion. The study demonstrates a distinct tense-lax phonation contrast in Yunshan Lahu, which is characterized by multiple types of phonation, differences between front and back parts of tense vowels, and equal importance of tense-lax contrast and vowel length. To contribute to a systematic description of Tibeto-Burman language, this paper proposes to treat tense-lax contrast as the main feature in phonological induction, using length as its accompanying feature for explanation. From the perspective of the path of historical evolution, tenseness comes from the loss of plosive codas, and is also closely related to voiced, aspirated initials. In the process of transforming tense-lax features to tones, tense vowels retained their features of tenseness as a result of falling tones.

Vowel quantity/quality redux: Revisiting vowel contrasts in Hakha Lai monophthongs

Previous scholars have documented a phonemic length distinction in the monophthongal vowels of Hakha Lai, a Tibeto-Burman language spoken in Chin State in western Myanmar (Melnik, 1997; Peterson, 2003; Maddieson, 2004). In a previous pilot study of data from two college-aged speakers (the first instrumental acoustic analysis of Hakha Chin vowel quality), our findings revealed stark individual differences: one speaker showed robust quantity and minor quality differences, while for the other, neither duration nor quality played key roles; rather, her system had merged. Maddieson (2004) proposed that the length associated with long vowels in Hakha Lai is mainly realized through lengthening of sonorant codas; we did not find this to be the case for either speaker. However, those pilot data were limited both in terms of sample size and age range. Therefore, to expand on our previous findings, we now present analysis of data from fourteen talkers, including both a group of nine college aged talkers (6 women) and five older talkers (2 women, ages 46 and 77; 3 men, ages 48, 60, and 62). Duration and quality measures are reported for all monophthongs in all possible syllable shapes.

An ultrasound investigation of Hnaring Lutuv (high?) vowels

Lutuv (also known as Lautu) is an under-documented Chin language from the Tibeto-Burman language family spoken by 18,000 people, both in Chin State in western Burma and in diaspora communities worldwide, including approximately 1000 people in the Indianapolis Chin refugee community. Lutuv utilizes a typologically rare six-way contrast in the higher part of the vowel space (i y ɨ ʉ ɯ u, see Bohnert et al. 2022), with an additional four high diphthongized vowels (ie̯ yə̯ ɯə̯ uo̯). Previous work has also identified that the high central vowels (/ɨ ʉ/) are poorly disambiguated—acoustically, they show considerable overlap with both each other and the high back vowels, and in terms of lip posture, they do not display the characteristics of a typical rounding contrast (Bohnert & Berkson 2023). The present work utilizes 3D ultrasonography to provide detailed lingual articulatory data of Lutuv vowels with special attention paid to the high central vowels, adding a new dimension to the existing acoustic and articulatory data. Real-time images of tongue position and motion provide new insights into the complex articulatory gestures involved in the production of these sounds and constitute the first ultrasound investigation into this underdocumented language.

Interrogatives of reason in Tibeto-Burman languages of Sichuan

Abstract This is a typological study of the why-interrogative expressions in Tibeto-Burman languages, or the non-Chinese Sino-Tibetan languages, in Sichuan, southwest China. After examining 22 languages/dialects, the interrogative category of reason is grouped into three types, viz. the distinct why-type, the how-type, and the what-type, according to the interrogative categories from which they are derived. It is discovered that the what-type is the dominant strategy for languages in Sichuan to derive the reason category. It is also common for Tibeto-Burman languages to use verbal interrogatives, namely interrogative verb phrases and interrogative words with verbal origins, dominantly in the sense of ‘to do what’ and ‘to become what’, to ask for reason. After a focused investigation of the verbal interrogatives, it is found that Tibeto-Burman languages in Sichuan distinguish purpose from cause via word/phrase distinction, sentential positions and semantic differences. A path of grammaticalization of the verbal interrogatives is thus proposed and analyzed. Finally, the derivation maps of interrogatives in Cysouw (2005) and Hölzl (2018) are complemented with a refined distinction between purpose and cause.

Sortal classifiers and noun categorization in Zauzou

Abstract This paper investigates the sortal classifier system in Zauzou, a Tibeto-Burman language spoken in Southwest China. Three etymological subclasses – repeater, non-repeater, and quasi-repeaters – are identified in two morphosyntactic contexts: the bare classifier phrase [n+clf] and the full noun phrase [n+mod+clf], serving as an “individualizer” that transforms unindividualized nominal concepts into referential individuals. The three types of classifiers classify nouns on the basis of different semantic parameters that differ in terms of semantic contrastiveness. Animacy, shape, size, rigidity and quanta are non-contrastive semantic parameters commonly found among non-repeaters. Repeaters and quasi-repeaters categorize nouns primarily on the basis of semantically contrastive taxonomy, meronomy, or arrangement. With respect to the function of quantification, repeaters, quasi-repeaters, and non-repeaters are identical in [n+mod+clf] but diverge in [n+clf]. They do not uniformly render the singular interpretation with all kinds of referents in [n+clf]. Non-repeaters are more grammaticalized classifiers than (quasi-)repeaters. The Zauzou data provide evidence for the development from repeaters to non-repeaters, on a par with the commonly recognized grammaticalization path from nouns to classifiers, which is conditioned by two types of “parameter shift”. This study offers a descriptive model that effectively captures the relationship between semantic-functional properties of sortal classifiers and their historical development in “repeater” languages.

Phonological, lexical and grammatical borrowings and replications in Hyow, a language of the Bangladesh-Burma border area

Abstract This paper presents a discussion of contact-induced borrowings and replications in Hyow, a Southeastern South Central (SC) Tibeto-Burman language spoken in the Chittagong Hill Tracts of Bangladesh. Hyow shows two layers of contact-induced changes: an earlier layer under the influence of Burmese, and a more recent layer under the influence of Bangla. The Hyow desiderative -sháng closely resembles the suffix shɔn ‘want to’ in the Burmese variety of Rakhine State, suggesting that Hyow speakers previously lived in Rakhine State. In its current location, Hyow speakers are in contact with Bangla, and the presence of Indo-Aryan type relative-correlative clauses in Hyow – not found in any of the SC languages in Burma – reveals the effect of this recent contact with Bangla. Apart from demonstrating the respective antiquity of Hyow contact with Burmese and Bangla, the two examples of the borrowing of the desiderative suffix -sháng and relative-correlative clauses also show borrowing and replication as two distinct types of contact-induced change (Heine and Kuteva, 2005, 2006). This paper gives the first account of phonological, lexical and grammatical borrowings and replications to understand how language contact has shaped Hyow.

The role of cognitive schemas in linguistic convergence

Abstract This article reports on some outcomes of language contact and linguistic convergence involving Tibeto-Burman and Indo-Aryan languages in the Northeast Indian state of Nagaland. The primary focus falls on Nagamese, a lingua franca of the region that is undergoing a change in its morphosyntactic alignment typology. Evidence is presented to demonstrate that cognitive schemas are most likely responsible for the spread of replicated case marking patterns from local Tibeto-Burman languages to Nagamese, and that this has triggered a change in the alignment pattern of Nagamese over the past fifty years. The data presented in the paper are significant for demonstrating how language contact and the replication of cognitive schemas can be plausible drivers of grammatical change, even for something as fundamental to the syntax of a language as its morphosyntactic alignment.

Jinghpaw loanword typology

Abstract Jinghpaw is a Tibeto-Burman language spoken in northern Burma and adjacent areas of China and India. The language is known for both its conservative nature (e.g., comparative Tibeto-Burman linguistics) and the innovative nature of its speakers (e.g., social anthropology of highland Burma). In view of this duality, this paper explores the Jinghpaw lexicon asking whether it is conservative enough to shed great light on the reconstruction of the proto-language or whether it is innovative, having undergone a grand-scale lexical replacement under intensive contact. This paper addresses this question by measuring the lexical borrowing rate in the language based on the methodology laid out by the Loanword Typology (LWT) project. The results put Jinghpaw among average borrower languages in terms of the borrowability scale of the world’s languages. This study concludes that the Jinghpaw lexicon, especially its basic vocabulary, is relatively conservative, and the semantic fields affected by borrowing are mostly restricted to those that show high cross-linguistic susceptibility to intercultural influences. The results and discussion in this paper enable further understanding of comparative Tibeto-Burman linguistics and contact linguistics of northern Burma and beyond.

Revisiting “Eye of the day”

Abstract A particular lexical construction for “sun” composed of morphemes for “eye” and either “day” or “sky” has been widely reported for Austronesian languages. Urban (2010) made the case for this phenomenon as an areal feature originating in Austronesian, with attestation in Austroasiatic and Tai-Kadai varieties, but absent in Sino-Tibetan. A follow-up (Blust 2011) argued for the possibility of independent genesis across the languages, while reiterating the absence of the feature in Sino-Tibetan. This paper presents a large scale survey of Tibeto-Burman language varieties. Data from this region show widespread occurrence of the phenomenon in distinct constructions, arguing against contact as the inciting factor. Instead, this paper argues for multiple innovation events, with only small scale regional spread through contact. Data are analysed from approximately 250 doculects from a wide range of sources, including newly elicited data for Bodo-Garo, Maringic and Northern Naga varieties.

Distinguished biological adaptation architecture aggravated population differentiation of Tibeto-Burman-speaking people

Tibeto-Burman (TB) people have endeavored to adapt to the hypoxic, cold, and high-UV high-altitude environments in the Tibetan Plateau and complex disease exposures in lowland rainforests since the late Paleolithic period. However, the full landscape of genetic history and biological adaptation of geographically diverse TB-speaking people, as well as their interaction mechanism, remain unknown. Here, we generate a whole-genome meta-database of 500 individuals from 39 TB-speaking populations and present a comprehensive landscape of genetic diversity, admixture history, and differentiated adaptative features of geographically different TB-speaking people. We identify genetic differentiation related to geography and language among TB-speaking people, consistent with their differentiated admixture process with incoming or indigenous ancestral source populations. A robust genetic connection between the Tibetan-Yi corridor and the ancient Yellow River people supports their Northern China origin hypothesis. We finally report substructure-related differentiated biological adaptative signatures between highland Tibetans and Loloish speakers. Adaptative signatures associated with the physical pigmentation (EDAR and SLC24A5) and metabolism (ALDH9A1) are identified in Loloish people, which differed from the high-altitude adaptative genetic architecture in Tibetan. TB-related genomic resources provide new insights into the genetic basis of biological adaptation and better reference for the anthropologically informed sampling design in biomedical and genomic cohort research.

Assamese and BODO next Word Detection using LSTM

The official language of the Indian state of Assam is Assamese, an Eastern Indo-Aryan language. Assamese, the sole native Indo-Aryan language in the Assam Valley, has been heavily impacted by the nearby Tibeto-Burman languages in terms of lexicon, phonetics, and grammar. Its grammar is renowned for its highly inflected forms, and both honorific and non-honorific formulations can include a variety of pronouns and plural nouns. Additionally closely linked to Bengali, Assamese lacks grammatical gender distinctions like Oriya and Bengali. On the other hand, The Bodo language is a variety of dialects of the Tibeto-Burman branch of the Sino-Tibetan languages. Assam, Meghalaya, and Bangladesh are all home to speakers of the Bodo language, which is spoken in northeastern India. It shares linguistic kinship with the Dimasa, Tripura, and Lalunga languages and is written in Bengali, Latin, and Devanagari scripts. Another name for Next Word Prediction is Language Modeling. Predicting what word will be spoken right away requires commitment. It is one of the primary functions of NLP and has a wide range of uses. Our objective is to create this model as quickly and efficiently as possible. RNNs can interpret prior material and forecast words since they have a lengthy short-term memory, which might be useful for users when building sentences. This method creates words by using letter-by-letter prediction, or letter-by-letter prediction. Users can benefit from next word prediction, which makes typing faster and more accurate. The Assamese and Bodo languages rely on next word prediction since multiple characters can be created by pressing the same consonants combined with different vowels, vowel combinations, and special keys. As a result, we present a Long Short Term Memory (LSTM) network model for Assamese and Bodo next word prediction. With 63,300 point sentences, we test the suggested network model, and it achieves 96 per cent accuracy. In addition, we contrasted the suggested model with cutting-edge models like the LSTM. The proposed network model offers a promising outcome, according to experimental findings.

Elevation and fog-cloud similarity in Tibeto-Burman languages

Lexically, 52.99% of the Tibeto-Burman languages, the non-Sinitic branches of the Sino-Tibetan language family, treat fog as something identical or similar to cloud, based on our database of 234 Tibeto-Burman varieties; there are three lexical relations of such fog-cloud similarity in Tibeto-Burman languages, namely cloud colexified with fog, cloud as a hypernym of fog, and cloud as a formative of fog. The rest of the Tibeto-Burman languages use semantically disconnected words to describe fog and cloud. The high proportion of fog-cloud similarity in Tibeto-Burman languages, compared with that of the non-Tibeto-Burman languages spoken alongside the Trans-Himalayan region (i.e., 10.80%, a result based on our database of 213 non-Tibeto-Burman varieties), has its historical reason, namely the relics of Proto-Tibeto-Burman. However, other than the phylogenetic factors, an underlying reason can be attributed to the environmental influence. The present findings indicate that fog-cloud similarity is more likely to happen at higher elevations, particularly between the range of 1000 m to 3000 m above sea level. After reviewing the meteorological features, it is found that the Tibeto-Burman region has ideal conditions for the formation of low cloud, namely with high humidity and through orographic uplift due to the mountainous environment. Since Tibeto-Burman speakers live in high elevations, low cloud, the dominant cloud of the region, may surround them or beneath their view. Therefore, they may find it difficult or not necessary to distinguish fog from low cloud. Our conclusion is also supported by the languages of other families and regions, such as the Daghestanian languages of the Caucasus region and the languages of the Central Andes. Moreover, the present findings agree with the theory of efficient communication. That is, languages displaying fog-cloud similarity are adaptive to higher elevations with less communicative need to distinguish between the two concepts by using completely different and unrelated linguistic forms; on the contrary, languages displaying fog-cloud divergence have stronger need to do so, resulting as well from their adaptation to the extra-linguistic environment. Finally, tropical climates, another possible predictor for fog-cloud similarity, are identified as a future research direction.
