79 COHESION AND COHERENCE IN DISCOURSE GRAMMAR Tursunalieva Mukhlisa Bakhtiyor qizi, student of Oriental University Scientific advisor: Egamberdieva Shakhzoda Damirovna, Associate professor, PhD Oriental University Abstract. Discourse grammar is a branch of linguistics that studies how grammatical structures function in extended stretches of language such as conversations, narratives, and academic texts. Unlike traditional sentence-level grammar, discourse grammar emphasizes cohesion, coherence, and the pragmatic use of grammar in communication. This paper examines how grammatical choices contribute to cohesion, the creation of meaning, and the interpretation of discourse. Through a review of theoretical frameworks and examples, the study highlights the importance of cohesive devices such as reference, ellipsis, substitution, conjunction, and lexical ties. It also addresses coherence as a higher-level concept, showing how discourse grammar links grammatical forms with context and meaning. The paper concludes that cohesion and coherence are central to understanding how language users construct meaningful and connected communication in both spoken and written forms. Keywords: discourse grammar, cohesion, coherence, grammatical choices, extended texts Language is not merely a collection of isolated sentences. Communication, whether oral or written, unfolds in longer stretches of discourse that require more than knowledge of individual grammatical rules. Traditional grammar often focuses on the sentence as the main unit of analysis, but real communication requires understanding how sentences are combined into meaningful and coherent discourse. In this sense, discourse analysis and discourse grammar shift attention from isolated structures to the ways in which linguistic units interact across larger stretches of text. The central concern is not only what sentences mean in isolation but how they contribute to the cumulative meaning of the discourse. Discourse grammar provides a systematic framework for studying how grammar functions across extended texts. It investigates not only correctness at the sentence level but also the mechanisms of cohesion and coherence that bind sentences together, producing unity and interpretability. Cohesion ensures grammatical and lexical connectedness, while coherence secures logical and thematic integration across discourse. Together, they make communication comprehensible and purposeful. In addition, discourse grammar highlights the pragmatic dimension of grammatical choice, showing that the selection of tenses, voices, pronouns, and connectors is shaped by communicative goals, context, and audience expectations. 80 The study of discourse grammar emerged in the late twentieth century alongside the rise of discourse analysis and functional linguistics. One of the most influential contributions was Halliday and Hasanʼs Cohesion in English, which established cohesion as a central category of discourse. They identified five cohesive devices – reference, substitution, ellipsis, conjunction, and lexical cohesion – and showed how these linguistic mechanisms create unity beyond the sentence level. Their work remains the foundation for subsequent studies in discourse grammar. Later research emphasized the interaction between grammar and context. Thompson argued that discourse grammar bridges grammar and pragmatics, showing that grammatical choices depend not only on formal correctness but also on communicative purpose. Carter and McCarthy highlighted the idea of “grammar in use,” stressing that grammar should be understood dynamically, as speakers and writers employ it in authentic discourse. This perspective shifted attention from abstract structures to actual usage across communicative settings. Biber et al. extended this approach by analyzing grammar in spoken and written registers, demonstrating that discourse patterns vary depending on genre, mode, and communicative context. Their corpus-based research confirmed that cohesion and coherence are realized differently in everyday conversation, academic texts, and professional communication. More recent studies further underline the importance of coherence as a higher-level organizing principle, without which cohesive devices may remain insufficient for interpretation. Taken together, these contributions demonstrate that discourse grammar is not confined to sentence-level accuracy. It is a multidimensional framework that integrates cohesion, coherence, and pragmatics, offering insights into how grammatical choices construct meaning in extended discourse. This study is grounded in a functional and discourse-oriented approach to grammar, particularly drawing on Hallidayʼs Systemic Functional Linguistics (SFL). Within SFL, grammar is understood not merely as a set of prescriptive rules but as a resource for making meaning in context. Language is viewed as operating through three metafunctions: 1. Ideational metafunction – representing experience and the world; 2. Interpersonal metafunction – enacting social relationships; 3. Textual metafunction – organizing messages into coherent texts. Discourse grammar is closely tied to the textual metafunction, which concerns how sentences are structured into larger, connected units of communication. Cohesion, in this framework, represents the linguistic devices that knit sentences together, while coherence refers to the higher-level organization of discourse that ensures interpretability and relevance. This framework also incorporates cohesion theory, which emphasizes the role of reference, ellipsis, substitution, conjunction, and lexical cohesion in building textual unity. Cohesion is understood not in isolation but in relation to coherence: cohesive devices provide the formal links, whereas coherence results from contextual interpretation, shared knowledge, and logical organization of ideas. Furthermore, discourse-pragmatic perspectives highlight the communicative dimension of grammar. Carter and McCarthy argue that grammar in use reflects 81 speaker intentions, audience expectations, and situational context. Similarly, Biber et al. show that grammatical choices vary across registers, indicating that discourse grammar is sensitive to communicative mode and genre. By combining systemic functional linguistics, cohesion theory, and discoursepragmatic approaches, this study adopts an integrative framework. It allows for a nuanced analysis of how cohesion and coherence operate together to shape meaning across extended texts, whether spoken or written. Cohesion refers to the set of grammatical and lexical mechanisms that link sentences and clauses into a unified whole. It provides the surface connections that enable discourse to be perceived as continuous rather than as a sequence of unrelated sentences. As Halliday and Hasan demonstrated, cohesion is achieved through systematic use of linguistic devices that create semantic ties across a text. These ties guide readers or listeners in interpreting information and establish relationships between ideas. Halliday and Hasan identify five primary types of cohesion: 1. Reference – the use of pronouns, demonstratives, and definite articles to point backward (anaphoric) or forward (cataphoric) in a text. Example: Anna bought a book. She read it in one day. Here, the pronoun she refers back to Anna, and it refers to a book. Reference allows readers to track participants across discourse. 2. Substitution – the replacement of one item with another to avoid repetition. Example: I need a pen. Do you have one? The word one substitutes for pen, reducing redundancy while maintaining cohesion. 3. Ellipsis – the omission of an element that can be inferred from context. Example: Do you want tea? – Yes, I do [want tea]. The repeated element is omitted but understood, creating a cohesive link. 4. Conjunction – the use of linking words to signal logical or semantic relations between clauses and sentences. Example: It was raining, so we stayed indoors. The conjunction so expresses a cause-effect relationship. 5. Lexical cohesion – the use of lexical relations such as repetition, synonymy, collocation, or semantic fields to connect ideas. Example: The car was fast. That vehicle could reach high speeds. The relation between car and vehicle provides lexical continuity. These cohesive devices ensure that discourse functions as a meaningful whole rather than a string of disconnected statements. Importantly, cohesion operates across both spoken and written modes. In conversation, reference and ellipsis are particularly common as speakers economize language, while in written discourse, conjunctions and lexical cohesion are often used to structure arguments and narratives. In sum, cohesion provides the textual glue that holds discourse together. Without cohesive devices, communication would lack clarity and continuity, making interpretation more difficult for the audience. Yet cohesion alone does not guarantee overall textual unity; it must work in tandem with coherence to achieve full communicative effectiveness. This study has demonstrated that discourse grammar extends the boundaries of traditional sentence-based grammar by focusing on the mechanisms that create meaningful and connected communication across extended texts. Central to this 82 approach are the concepts of cohesion and coherence, which together ensure that discourse is both structurally unified and semantically interpretable. Cohesion provides the surface-level links through reference, substitution, ellipsis, conjunction, and lexical ties, while coherence establishes the logical and thematic relationships that make texts relevant and purposeful. The analysis has shown that grammatical choices – such as tense, aspect, voice, pronoun use, and sentence complexity – not only fulfill structural functions but also contribute directly to discourse meaning. These choices are shaped by communicative goals, context, and audience expectations, illustrating that grammar operates as a dynamic resource for meaning-making rather than as a static set of rules. By integrating cohesion and coherence, discourse grammar provides valuable insights into how speakers and writers construct effective communication. This perspective has important applications for academic writing, language teaching, conversation analysis, and digital communication, where both cohesion and coherence are necessary for clarity and impact. In conclusion, cohesion and coherence are not peripheral aspects of grammar but essential dimensions of discourse. They reveal how grammar links form and meaning at the text level, enabling communication to move beyond isolated sentences and toward coherent, purposeful discourse. Understanding these processes is therefore fundamental for linguists, educators, and students seeking to grasp how language functions in real communicative contexts. References 1.
