This study conducts a cross-disciplinary corpus analysis to unveil core lexical bundles in English research articles. Lexical bundles, defined as recurrent sequences of words, play a crucial role in academic discourse by facilitating coherence and efficiency in communication. By examining a diverse corpus of research articles spanning multiple disciplines, this study identifies and analyzes frequently occurring lexical bundles. Through computational linguistics methods and statistical analysis, the study elucidates patterns of lexical bundle usage across disciplinary boundaries. The findings contribute to our understanding of disciplinary variations in academic writing and shed light on the linguistic features that characterize research articles in different fields. Furthermore, the study explores the pedagogical implications of teaching core lexical bundles to non-native English speakers, aiming to enhance their proficiency in academic writing and discourse.
