The ecological structure and dynamics of seasonal migrations of passerines of the Putorana Plateau are analyzed. The route census method on transects of unlimited width is used. The Putorana Plateau is a junction of migration routes. Birds fly along the coastal-edge strip along rivers or lakes in the northern, western, eastern directions in spring, and in the southern, southwestern, western directions in autumn. Spring migration takes place from May 22 to June 20, lasts 8–17 days, for most species – 9–12 days. In the south of Putorana, spring migration takes place in a shorter time than in the north of the region. Autumn migration takes place from late July to late August, lasts 14–31 days, for most species – 20–26 days. During the entire migration, a more fleeting period of the main migration is expressed, when 70–80% of individuals fly. The bird population density in spring is 231, in autumn – 440 individuals/km². The population density is maximum in the south of Putorana, minimum in the north. Significant amplitude of daily abundance indices of species, asynchrony between phenological phenomena in different species and in individuals of the same species are characteristic. The course of migration is wave-like, with 1–4 bursts of migration activity per season. The intensity of migration is higher on days with the lowest air temperature. In autumn, synchronization of waves of maximum flight in related species does not occur. In spring, the dynamics of flight in related species varies in different years: from complete synchronization of waves of maximum flight to their absolute discrepancy.

In this work, a comprehensive modeling of the influence of short-range order on the mechanical properties of body-centered cubic high-entropy ZrTiNbV and ZrTiNbHf alloys under shear deformation using a hybrid molecular dynamics (MD) and Monte Carlo (MC) approach has been carried out. High-entropy alloys (HEA) are a new class of materials produced by mixing four or more elements in approximately equal proportions, providing a unique combination of properties and expanding the capabilities of traditional materials science. In recent years, special attention has been paid to the mechanical properties and deformation mechanisms of high-entropy alloys with a bcc lattice, where screw dislocations, interaction with atoms of various elements and the formation of short-range order, which contributes to the strengthening of the material, play a key role. Bicrystalline models with different degrees of atomic ordering resulting from MD/MC relaxation have been constructed, allowing for both chaotic and clustered elemental distributions. A comparative analysis of structural changes, defect evolution and mechanical properties (in particular, yield strength) under shear has been carried out. It was found that in ZrTiNbV alloy the formation of Nb clusters initiates local phase transformations BCC → HCP and reduces yield strength, whereas for ZrTiNbHf the formation of segregations and nanoclusters effectively prevents grain boundary migration and phase transformations, which leads to a significant increase in strength. The results are consistent with the current understanding of the role of near-order in the hardening of high-entropy materials and demonstrate that targeted control of chemical ordering and grain boundary structure can be an effective tool for optimizing the mechanical properties of high-entropy alloys. The work extends fundamental knowledge of plasticity and fracture mechanisms in multicomponent alloys and opens new perspectives for their application under high mechanical loads and aggressive environments.

This study presents the results of investigation into hemoglobin property alterations in cervical cancer (CC) patients before and after radiation therapy using Raman spectroscopy. Dry blood smears from CC patients and healthy donors were analyzed using a Raman spectrometer with 532 nm excitation wavelength. The results revealed significant impairments in hemoglobin’s oxygen transport function. Comparative analysis of spectral characteristics demonstrated higher oxyhemoglobin concentrations in the control group versus CC samples, indicating reduced oxygen-binding capacity in the pathological state. Peak shifts and intensity changes suggested increased deoxyhemoglobin fractions in CC patients. Analysis of key vibrational modes (991, 1127, 1165, 1300, 1337 cm⁻¹) confirmed conformational changes in the heme group and impaired oxygen-binding function. Particularly significant was the altered intensity ratio I₁₃₇₅/I₁₁₂₇ (2-5.5% difference versus controls), reflecting decreased R-state hemoglobin fractions. The study identified increased hemoglobin-NO complexes (20% rise in I₁₆₁₈/I₁₅₈₀) while methemoglobin levels remained stable. We also observed changes in erythrocyte physicochemical properties: increased membrane fluidity (35% higher I₂₈₅₀/I₂₈₈₀) and enhanced amino acid environment polarity (23% decrease in I₂₉₃₀/I₂₈₅₀) in CC patients. Radiation therapy exacerbated these changes, though its impact on oxygen-binding capacity was less pronounced than the oncological process itself.

In 1948, F. London calculated the quantum of magnetic flux from an electric current created by a single electron. The key condition for the calculation was ascribing a quantum of kinetic momentum ћ to the electron. In 1956, L. Cooper described two-particle systems of correlated electrons (Cooper pairs) arising in conductors as a result of electron-phonon interaction. Assigning a quantum of kinetic momentum ћ to a two-particle system leads to a twofold decrease in the calculated value of the magnetic flux quantum. In 1961, B.S. Deaver and W.M. Fairbank and independently R. Doll and M. Nebauer measured the quantum of magnetic flux. The result turned out to be half as much as F. London’s quantum. Since then, it has been believed that the quantum of magnetic flux is created exclusively by Cooper pairs and that it is half as much as F. London’s quantum. The aim of the study is to rethink the above circumstances. The geometric shape of an electron is unknown. However, it is believed that it is neither a ball nor a sphere. This follows from the formula of its classical radius. The complete uncertainty of the electron's shape allows its spin to be consistently represented as an angular momentum generated by a material point with the mass of an electron, rotating along a circle of an indefinite radius (arbitrarily small, and its value is of no importance). This approach may have shortcomings, but it also has a significant advantage in the form of the possibility of using a ready formula for the magnetic flux created by the “current” of one electron. In reality, there is the quantum of F. London, the quantum of magnetic flux caused by the electron spin, and their superposition (quasi-quantum).

This study presents a comprehensive numerical approach for evaluating and analyzing the resolution of digital holographic microscopes. The analysis focuses on five key factors that have the greatest impact on image reconstruction quality: object-to-sensor distance, temporal and spatial coherence of the illumination source, physical pixel size of the detector, and the optical field of view (FOV). For each of these factors, numerical modeling algorithms were developed and integrated into a unified software platform that enables systematic analysis without the need for physical experiments. This is particularly relevant for the development of compact and low-cost digital holographic microscopes. A wave propagation model based on the angular spectrum method was implemented, and simulations were conducted for a typical holographic microscope configuration. Validation of the results and resolution assessment were carried out using the USAF 1951 resolution target. It was found that the most significant limitations are associated with pixel size, object-to-sensor distance, and the size of the reconstruction area. Coherence properties of the source also affect resolution but can often be compensated for during the design phase. It is demonstrated that the developed algorithm enables preliminary estimation of the theoretical resolution limit for a given system configuration and identification of dominant constraints. The scientific novelty of this work lies in the integration of all major resolution-related factors into a single computational environment, enabling numerical optimization of digital holographic microscope parameters during the design stage. The proposed approach can be applied in the development of portable holographic microscopes for applications in biomedicine, microplastic monitoring, and other practical domains.

The article examines the influence of state memory policy on the depiction of the national past in the literature of the peoples of Siberia during the period 1940–1980. Based on the materials of Altai, Buryat, Khakass, and Yakut literatures, it demonstrates that the representation of national history in Soviet-era works was closely intertwined with the concept of “friendship of peoples”. According to this concept, the peoples of Siberia initially entered into friendship with the Russians from the outset and voluntarily acceded to the Russian state, resulting in exclusively positive outcomes for their historical destinies. Literary texts constructed a historical narrative that aligned with state rhetoric and scholarly works of that period. Central to this narrative is the accession to Russia, presented as a pivotal moment in national history and functioning as a founding myth. The pre-Russian past was portrayed as a time of darkness and privation. The accession to Russia is depicted as the acquisition of kind and selfless friends in the form of the Russian people and the Russian state, who assume guardianship over the indigenous peoples and pave the way for a more prosperous future. The post-accession era is presented as a period of continuous improvement. Significantly, this historical narrative exhibits a hierarchical view of the relationship between the state and its constituent peoples, assigning them unequal roles in the historical process. Russia is conceived as the center of civilization and progress, with the Russian people cast as the primary agents of its achievements. Simultaneously, the peoples of Siberia are depicted as initially situated outside the bounds of civilized society, with alliance with Russians on terms of “younger brothers” presented as the sole means of acceding to world civilization and progress. This perspective on the past of non-Russian peoples reinforced the notion of their inextricable bond with the state, outside of which no felicitous future or national development was conceivable.

This study addresses the scientific problem of the limited understanding of the unique characteristics of the Russian-language literary fairy tale genre in Buryatia within the region’s contemporary literary landscape. Modern literary fairy tales in Buryatia artistically synthesize mythological foundations with literary traditions and demonstrate a fusion of diverse cultures. The aim of this research is to identify the specific features of the fairy tale genre at the intersection of these cultures. The literary fairy tale “Grandpa Pusuu’s dragon” by Erzhena Batorova serves as the source material for this study. The methodology incorporates principles and techniques from comparative-historical literary criticism, alongside psychological approaches to literary analysis. Erzhena Batorova’s “Grandpa Pusuu’s dragon” is defined as a literary fairy tale. The analysis of the work’s ideological and artistic structure is conducted within the context of mythological and folklore traditions. The study examines the interplay of Russian, Buryat, and Chinese artistic traditions, defining the specific nature of its intertextuality. It also reveals the significance and role of myth and oral folklore in the development of the literary fairy tale genre. The analysis identifies motifs of magic, journeys, transformations, initiation, the spiritual path, exchange and deception, illness, return, disruption and the restoration of order. The realization of archetypal figures – the child, the shadow, and the trickster – is explored. The author’s reinterpretation of folklore heroes, such as the seeker, the victim, the antagonist, the helper, and the giver, is investigated. The correlation between types of heroes and their associated functions is established, and the scope of their actions is examined. The authorial perspective is revealed through an analysis of elements from folk cultures. The study identifies the inadequacy of the semantics of mythological images and the disruption of the sequence of hero functions. The individualization and increasing complexity of the author’s fairy tale characters, whose images are rooted in folklore, are traced. The practical significance of this research lies in enriching theoretical knowledge of the modern literary fairy tale genre in Buryatia. Future research directions may involve further investigation of the Russian-language literary fairy tale genre.

This study examines the forms of address employed by teachers in Algeria and Russia, focusing on their cultural significance, student preferences, and the underlying power dynamics in educational settings. Drawing on sociolinguistic and pragmatic frameworks, the research investigates how teachers and students navigate authority, respect, and social hierarchy through language use. The study includes 143 participants from Algeria and Russia, encompassing teachers and students across various educational levels, allowing for a comparative analysis of cultural and contextual influences on classroom discourse. Data collected from classroom interactions reveals the significance of address forms—such as titles, pronouns, and honorifics–in constructing and negotiating power relationships. The findings highlight the dual role of politeness strategies: maintaining hierarchical structures while fostering a collaborative learning environment. It has been noticed that Algerian teachers predominantly use first names, last names, honorifics, and kinship terms, reflecting the societal emphasis on familial bonds and respect. Conversely, Russian teachers utilize first names, first names combined with patronymics, last names, and endearment terms, embodying a blend of formal respect and nurturing communication. However, the students' preference for informal address forms reveals a shift towards reducing power imbalances, promoting a more collaborative and inclusive classroom atmosphere. This paper contributes to understanding the sociocultural underpinnings of classroom discourse in multilingual and multicultural contexts, offering insights into the broader relationship between language, power, and education.

The purpose of the article is about identifying some characteristic aspects within discursive strategies refracting the Graecophilian practice. Firstly, discourse analysis is now becoming a more influential area for research within a number of humanitarian disciplines that can include sociology, sociolinguistics, psychology, anthropology, linguistics, linguo-philosophy, and communicative activity considered as a linguistic phenomenon. Secondly, the communicative approach to studying as well as teaching language oriented towards practical communicative activity has led to the need to analyze specific examples of how linguistic means are used (in written and oral forms) in order to improve the effectiveness of methods for language learners, as well as to attract more necessary linguistic material, one of whose inexhaustible sources is currently the global Internet. Notably, the Bible covertly speaks to man for God and greatly affected mankind’s fate since it decided the course of thought models for ages. Our study focuses mainly on the aspect of this influence which is linguo-philosophical. This view is seen via Graecophilian practice’s lens. The monograph considers the issue about interlingual and interdiscursive interaction through translations of the Bible. Above all, it points out that the internal form for language does not exist “in itself” because an individual with his own comprehension of the world expressed in language communicates at the very centre of speech. The medieval Graecophile linguo-philosophical tradition, based on the awareness of the inherent essence within the word, language, and grammar, bears a significant relationship to textual translation. This connection stems from its close alignment with what is termed “language ideology”, which encompasses beliefs about the nature of language, its manifestation in diverse contexts, the governing principles for constructing written and oral discourse, and the fundamental tenets of translation – specifically, the purpose and means by which meaning is cultivated, articulated, and preserved.

This article examines science fiction discourse from the perspective of ecolinguistics and cognitive linguistics. The primary focus is on the analysis of the “plant” frame and the identification of linguistic mechanisms that contribute to the formation of environmental values in science fiction narratives. The potential of ecolinguistic analysis for reconstructing the concept of “plant” is explored. The empirical basis of the study is Sue Burke’s novel “Semiosis”, in which the theme of alien flora is represented through the “plant” frame. The relevance of this topic is determined by global environmental challenges and the growing need to reconsider the traditional view of nature as an inexhaustible resource. The problem addressed in this study lies in the fact that contemporary linguistic practices often support an anthropocentric discourse that legitimizes environmental exploitation, despite the existence of alternative biocentric models. The aim of the research is to determine how science fiction discourse, through frame-slot analysis, contributes to the development of environmentally responsible thinking. To achieve this goal, the study sets the following objectives: to analyze the lexical and stylistic devices used in the text; to systematize the slots of the “plant” frame; and to assess the influence of employed discursive strategies on the perception of nature. The methodological foundation of the study is based on the principles of cognitive linguistics and ecolinguistics, which allow for the identification of ideological orientations embedded in language and their effect on ecological consciousness. Using frame-slot analysis, two key subframes are identified: “plant structure” and “plant intelligence”. The study analyzes the lexical and stylistic means through which plants are represented as active participants in the ecosystem. The results show that the traditional frame “plant = passive natural object” is transformed in science fiction discourse into “plant = active subject”. This transformation is articulated through lexical expressions of agency and intelligence, as well as through descriptions of strategic behavior, morphological adaptability, and chemical defense mechanisms. The findings demonstrate that the language of science fiction not only reshapes conventional frames of perceiving nature but also facilitates the formation of a sustainable, ethically oriented biocentric worldview, which challenges traditional anthropocentrism.

In recent decades, the study of aspect typology, which involves examining different aspectual meanings and their expression across various languages, has advanced significantly. Challenges arise in transferring aspectual semantic components into another language, especially when the target language lacks a corresponding grammatical category. To facilitate the transfer of Russian verb forms’ semantic nuances into Vietnamese, this research employs an onomasiological approach. This approach helps to overcome terminological diversity and allows us to present the object of comparison as transparently as possible: from semantic features to the means of their expression in different languages. The aim of this article is to identify how Vietnamese conveys the particular aspectual meanings of Russian verbs and to determine the patterns of their use in translating Gogol’s Dead Souls. The study analyzes verb forms from the first three chapters of the text (1034 instances and an equal number of Vietnamese equivalents) selected through continuous sampling method. The analysis reveals that Vietnamese has many specialized words capable of expressing aspectual features. For instance, particles such as đã, xong, rồi, được, hết, lên are used to express integrity and efficiency associated with perfective verbs. Meanwhile, words like cứ, mãi, vẫn, còn, được, có, lại convey meanings of processiveness, repetition, and general-factual significance, which are key aspectual meanings of imperfective verbs. A notable feature of Vietnamese is that the necessity of these specialized words can vary, and aspectual indicators might not always be needed if the aspectual semantics are supported by context. Our observations suggest that contextual elements play a significant role in cases involving imperfective verbs. The analysis indicates that perfective meanings do not require contextual elements, and the Vietnamese perfective markers may not be used. This is because perfective verbs describe single, completed events or situations at a specific point in the past. In narrative texts, which present past events as a sequence of actions, perfective verbs are prevalent. As a result, Vietnamese readers, lacking explicit perfective markers and contextual aids, may interpret these actions as single, completed events with a specific outcome.

The article presents the results of an analysis of ergonyms in Yakutsk. The study focuses on commercial names of grocery stores and food service establishments (restaurants, bars and banquet halls). This topic is of interest due to the dynamic development and evolution of ergonyms in Yakutsk, with the emergence of new strategies for attracting potential customers and service users. This opens avenues for further investigation of ergonyms, as their study constitutes an important direction in understanding the regional specificity of urban speech. The linguistic landscape of Yakutsk is multifaceted and diverse, encompassing numerous ergonyms that warrant comprehensive linguistic study. The scientific novelty of this research lies in the description and integrated study of ergonyms in Yakutsk, an area that remains under-explored. A systematic analysis of Yakutsk ergonyms, incorporating previous research, has not been conducted previously, underscoring the relevance of this study. The aim of this research is to identify the main characteristics of ergonyms, new methods of influencing potential customers, and specific features of ergonym functioning within the linguistic landscape of Yakutsk. We examined city ergonyms from various perspectives, constructing a motivational classification of ergonyms, analyzing ergonyms, and determining strategies for attracting potential consumers of goods and services. The article analyzes a continuous sample of ergonyms from the information system website “2GIS”, the Internet portal “Ykt.ru”, materials from the information agency LLC “Yellow Pages, 1997-2025” and personal observations. The practical value of this study lies in the fact that the methodology proposed in the article for analyzing regional ergonyms can be applied to the study of commercial names in other regions. Furthermore, a comparative aspect of ergonyms in different cities of Russia could be the direction of further research, in order to find the reasons for the similarities and differences in these systems. The research methodology is based on the identification, description, enumeration, and linguistic analysis of ergonyms in the town of Yakutsk.

The article is devoted to the study of phraseological units, proverbs and sayings in Russian, Yakut and English. The relevance of the research is due to the increased scientific interest of modern linguistics in the field of phraseology, as a cultural code for the national and cultural specifics of the people. The cultural value of phraseological units, proverbs and sayings is that they embody the figurative embodiment of the cultural and national worldview of the people, which makes it possible to better understand the mentality, national identity, and life experience of the people. Based on the conducted research of Yakut, Russian and English phraseological units, sayings and proverbs, which include the names of ancient non-metric measures of length, it can be concluded that in the old days, the peoples had a peculiar system of length measures resulting from labor practice and everyday experience. Summarizing the observations, we came to the conclusion that the most measures of length were based on the human body and were measured using hands, feet, that is, body parts, as evidenced by phraseological units, proverbs and sayings. Phraseological units, proverbs and sayings, possessing a national flavor, vividly demonstrate the history, culture, way of life and social reality of the past. Studying the history of one’s people in any aspect connects generations, ensures cultural continuity, and contributes to the preservation of national culture. The purpose of the work is to study Yakut, Russian and English phraseological units, proverbs and sayings, which include the names of ancient non-metric measures of length. The study is based on a comparative analysis of phraseological units, proverbs and sayings with a lexical component of the names of ancient non-metric measures of length.

This article examines folded and expanded propositions in the German-language texts of football fans’ banners, which they use during the matches of the first and second Bundesliga. The relevance of this study is determined by the fact that football is the most popular sport among fans all over the world and therefore their discourse requires separate consideration. The scientific novelty of the study is that in the German-language texts of football fans’ banners, folded and expanded propositions are being studied for the first time. The purpose of this work is to examine the ratio between folded and expanded propositions in banner texts and to identify the pragmatic intention of using a particular structure. Banner texts were selected as the research material, in which folded and expanded propositions were revealed. The classification of statements posted on the banners of German football fans is based on the ratio of folded and expanded propositions. The order of consideration involves analyzing banner texts containing an expanded proposition in the first part and a folded one in the second, and then options are proposed in which the folded proposition precedes the expanded one. The research used general scientific methods of cognition (analysis, synthesis, generalization, comparison). The study revealed that when a folded proposition is positioned at the beginning of the syntactic structure, the context and theme of the utterance are revealed even with the compression use of linguistic means. The expanded proposition in the second part of the syntactic structure complements the theme foregrounded at the beginning of the text. By the position of expanded proposition, at the beginning of the syntactic structure, for the most part, a description of the situation or the addressee is given, a specific topic is introduced, but the context of the situation is not always or not fully revealed. Folded proposition makes up for the omission of an expanded proposition, reveals its theme, can complement it, allows to understand what the purpose of the whole maxim is, while the form makes it concise and expressive.

The article analyzes the narrative structure of Konstantin Vaginov’s novel, “The Works and Days of Svistonov” (1928-1929), focusing on a comparison of the authorial and character-based narratives. The study aims to demonstrate the specific nature of their interdependence and mutual conditionality. The work’s relevance stems from the general philological interest in Russian avant-garde literature, the development of which was curtained by the imposition of party control over literature, as well as from the unique composition of the “novel within a novel”, which obscures independent authorial voices. The perspectivity of this research is conditioned by the synchronicity between the cultural situations of the 1920s and the 2020s, specifically concerning the problem of literature’s overload with cultural signs from eras, which paradoxically leads to alienation from the past. Vaginov imbues Svistonov’s text with elements of his own narrative, while the latter incorporates elements selected by Svistonov for his own novel. Both narratives are significantly influenced by cultural codes of the past. Consequently, it is concluded that the external fictional text is built upon another, internal fictional text, and literature is reduced to the recognition of self- and other-quotations. At the level of narrative structure, the study identifies features of recursiveness, or literary autophagy, correlating with the idea of the thanatocentricity of creativity, references to which are present in “The Works and Days of Svistonov” and have been previously described by the other interpreters of the novel. Specific objectives include identifying the creative methods of both narrators, Vaginov’s philosophical views on the nature of creativity and culture as an aggregate of signs expressing universal human experience, examining the visual code pf the novel, and analyzing the ontological status of fictional and real world.

The article explores the anthropological dimension of the image of the Bashkir people, one of the ethnic groups inhabiting the Russian Federation, as presented in literary works. The study employs SWOT analysis, a methodology traditionally used in business and now adapted for literary analysis. SWOT, an abbreviation for Strengths, Weaknesses, Opportunities, and Threats, is applied here to provide a structured framework for examining the literary-anthropological portrayals of the Bashkir people created by both Bashkir and Russian writers, poets, and playwrights. The absence of formalized economic categories in the general SWOT framework allows its application across various disciplines, including the humanities, making it well-suited to constructing an objective view of these literary images. Strengths: This section examines literary-anthropological images of the Bashkir people that reflect the strong aspects of the characters, highlighting models of behavior deemed worthy of emulation. Weaknesses: This section analyzed literary-anthropological images of the Bashkir people that reflect the weaker aspects of the characters. These weaknesses, as portrayed by the authors, represent shortcomings and limitations that may hinder development. These are vulnerabilities consciously included in the literary works to create contrast and accentuate the strengths of the positive image of the nation. Opportunities: This section explores images of the Bashkir people that reflected in Russian literature, which highlight positive qualities and play a significant role in creating a positive image of the nation. Threats: This section addresses negative images of the Bashkir people in Russian literature, which significantly damage the image of the nation and are beyond the direct control of the Bashkir people themselves to prevent. The aim of the study is to present a literary-anthropological image of the Bashkir people in a broad temporal and spatial perspective.

The article examines the influence of manipulative tactics and linguistic means on mass conscious in political propaganda media discourse of the US president, Donald Trump. Current geopolitical situation in the world is causing changes not only in the society and entire states, but also in political communication as well. That’s why communication mechanisms of political propaganda media discourse are of particular interest to researchers, since they are manipulative in nature and aim to change the recipient’s behaviour and his perception of reality. Analysing the American leader’s speech can help us understand his premeditated tactics in combination with particular linguistic means that allow him to achieve his goals. Donald Trump mostly uses the tactics of self-presentation, insult, inducement, reprogramming and “shooting the messenger”. His phrases are full of lexical repetitions, language units with negative connotations, as well as different stylistic techniques such as syntactic parallelism and rhetorical questions. Aggressive speech strengthens the influencing potential of his statements and propaganda rhetoric of the speaker himself. Thus, the study of the influence of manipulative tactics on mass audience allows to find them in the moment of communication and better understand the principles of their functioning. Moreover, it can help to determine the decree of their influence on the addressee. This material can be useful in linguistics, politics, diplomacy, intercultural communication and other fields where the ability to form an effective interaction between the addresser and the addressee is quite important.

This study investigates Russian and Evenki hydronyms of South Yakutia from a linguocultural perspective. Hydronymy of both Russian and Evenki origin serves as a valuable source of information regarding the unique of each group’s national worldview, as the linguocultural approach enables the elucidation of interrelationships between language, culture, history, and the worldview of the respective ethnic groups. The relevance of this work stems from the necessity for a comprehensive examination of the ethnographic, cultural, and ideological specificities of the Russian and Evenki toponymic landscape of South Yakutia. The aim of the study is an ethnolinguistic description of the hydronymy of South Yakutia, focusing on a comparative analysis of Russian and Evenki names of bodies of water, with the goal of identifying linguocultural features that reflect ethnic identity. To achieve this aim, the following objectives were formulated: to analyze the etymology of names for rivers, streams, and lakes; and to identify specific characteristics that determine the classification of hydronyms within the considered linguistic and cultural traditions. The research employs the following methods: an ethnolinguistic approach to determine the interrelationships between the linguistic forms of hydronyms and the cultural, historical, and religious beliefs of the corresponding ethnic groups, as well as comparative and quantitative (measurement) methods. The analysis of toponym characteristics facilitated the identification of unifying and differentiating factors in comparison to other groups, acknowledging the differential prisms through which each group perceives and interacts with the surrounding world.
