Book Reviews in Sciences: Structural and Functional Differences in Lexical Bundles

Lexical bundles are recurrent multi-word sequences that play a crucial role in academic discourse. This article presents an analysis of lexical bundles in book reviews across the disciplines of human and natural sciences. Drawing from a corpus of ۷۳۷ book reviews, the study investigates the functional roles and structural patterns of these recurrent linguistic units. The research aims to bridge a gap in the literature by exploring how lexical bundles vary across disciplines. Employing a quantitative-qualitative approach, the study first quantitatively identifies the most common ۴-word lexical bundles and compares their distribution between the two disciplines. The researchers then qualitatively analyzed the context in which these bundles are used, observing that they often serve to refer to or evaluate the structure, content, audience, or scope of the book under review. Findings reveal that while both human and natural sciences book reviews share some lexical bundles, they exhibit variations in their distribution, structures, and functions. Notably, natural sciences book reviews employ a greater frequency of lexical bundles signaling an evaluative context, particularly contexts related to the assessment of a book. The study also uncovers differences in the structural preferences of lexical bundles between the two disciplines. This research contributes to a deeper understanding of the genre-specific utilization of lexical bundles and underscores their role in conveying evaluative meaning in scholarly discourse. Furthermore, the study suggests avenues for further exploration, providing a foundation for future investigations into the intricate interplay between linguistic features and disciplinary preferences.
