    This study investigates LLM hallucinations as linguistic patterns emerging at the interface of contextual constraints and intrinsic knowledge, operationalized as a failure of contextual faithfulness. Moving beyond top-down error-injection, this research adopts a bottom-up inductive approach to analyze spontaneous linguistic elaboration. To ensure selection validity and avoid self-referential evaluation, 341 high-purity cases were extracted from 10,360 Wikipedia-based QA pairs through automated pre-screening and expert linguistic verification. Results show that models prioritize narrative coherence, primarily through ‘Causal Narrative Reconstruction’ (35.48%) and ‘Target Property Reconstruction’ (32.26%). Notably, ‘Input Premise Modification’ exhibited the highest syntactic complexity, with an average of 64.8 characters. These findings reveal that LLMs utilize specific linguistic markers and syntactic expansion to maintain internal coherence. By identifying concrete predictive features—such as contrastive particles and sentence length—this study provides an empirical foundation for robust detection strategies, bridging descriptive analysis and practical mitigation. - COLLAPSE

    This study aims to empirically investigate the semantic differences between the French near-synonyms façon and manière using corpus-based data and to explain these differences in terms of conceptualization. While previous studies have largely relied on intuitive definitions or limited examples, systematic empirical evidence from actual usage remains insufficient. Using a large-scale French corpus in Sketch Engine, this study examines major syntactic patterns and compares collocational behavior through logDice and ΔlogDice measures. The results show that façon is associated with collocates related to the internal realization of events, whereas manière tends to co-occur with evaluative and interpretive expressions. These differences are consistently observed across patterns, highlighting distinct conceptualization tendencies. This study contributes to strengthening the empirical basis of near-synonym research. - COLLAPSE

    An Analysis of Modal Verb Misuse among University Learners in Relation to Textbook Input

    This study conducts an error analysis of English modal verbs among university students and examines how these errors relate to their presentation in English textbooks. A diagnostic test was administered to 97 students, and 20 high school English I and English II textbooks were analyzed. The results showed that accuracy varied by semantic function, with epistemic modality yielding lower accuracy (M = 46.6%) than form-focused items (68.2%). Textbook analysis revealed a similar pattern: activities were concentrated on deontic modality, while epistemic meanings were presented less frequently. Most activities focused on form and meaning selection, with limited opportunities for pragmatic use and production. These findings suggest that learners’ difficulties stem not only from insufficient grammatical knowledge but also from limited exposure to meaning and use in context. Therefore, instruction should integrate form, meaning, and use through contextualized and discourse-level tasks. - COLLAPSE

    From Threat to Challenge: A Stress and Coping Perspective on EFL Graduate Students’ Academic Writing Process

    This study aims to explore EFL graduate students’ academic writing experiences and their developmental process at a university. Grounded in the transactional theory of stress and coping, an analysis of qualitative reflections from 17 participants revealed a three-phase process of stress adaptation: appraisal, coping, and reappraisal. Initially, students appraised high-stakes writing tasks as a ‘threat’ due to the gap between rigorous academic demands and their limited linguistic resources (Phase 1). However, this anxiety was effectively reduced through the mobilization of dual coping strategies (Phase 2). They utilized AI tools as problem-focused resources to overcome linguistic barriers, while simultaneously seeking teacher feedback as an emotion-focused resource for validation. This synergistic support facilitated a cognitive reappraisal, transforming the initial threat into a manageable ‘challenge’ and fostering students’ identities as independent scholars (Phase 3). The findings suggest a pedagogical paradigm shift toward a hybrid instructional model, where AI-driven efficiency and human-driven empathy coexist to cultivate confident, autonomous writers in the digital era. - COLLAPSE

    When Does Culture Matter? An Interactional Activation of Cultural Relevance in ELF Communication

    The role of culture in intercultural communication remains contested, with some studies emphasizing its contribution to miscommunication and others questioning its relevance. Moving beyond this dichotomy, this study examines when and how culture becomes relevant—or remains backgrounded—in interactions conducted in English as a lingua franca (ELF). Drawing on naturally occurring informal ELF interactions among speakers with diverse linguistic backgrounds, the analysis adopts an interactional perspective informed by conversation analysis and discursive pragmatics. The findings show that culture is not inherently salient but becomes relevant when participants orient to it in specific interactional contexts, particularly in moments of communicative trouble, identity positioning, and accounts for perceived differences. Crucially, in many cases participants achieve mutual understanding without invoking cultural categories. This study thus builds on interactional approaches to culture, offering a more fine-grained account of how cultural relevance is contingently achieved in EFL communication. - COLLAPSE

    Prosodic Marking of Second Occurrence Focus in Korean

    This study examines the phonetic realization of second occurrence focus (SOF) in Korean and its implications for the prosodic phonology-pragmatics interface. First occurrence focus (FOF) and SOF in controlled discourse contexts were obtained from a production experiment. Acoustic measures of duration, F0, and intensity were statistically analyzed. The results show that SOF lacks robust prominence in F0 and intensity, though limited durational differences and subtle F0 variation emerge under finer analyses. The presence of the focus particle –man also affects pitch realization. These findings suggest that SOF in Korean is neither fully prosodically marked nor purely pragmatic, but instead reflects gradient, language-specific interactions between prosody, morphosyntax, and information structure. - COLLAPSE
