Words, Frequencies and Functions: A Corpus Linguistic Investigation of Academic Writing

Abstract

Academic writing is shaped not only by individual words but also by recurring lexical and multi-word patterns. Therefore, examining how often these patterns occur and what they do in context provides a clearer understanding of academic communication. This study aims to examine the frequency, distribution, and functions of recurring lexical and multi-word patterns in academic writing. Furthermore, it investigates how these patterns contribute to meaning, cohesion, argumentation, academic style, and the construction of an academic voice. A corpus-based approach is employed using authentic academic texts. Frequency lists, concordances, clusters, n-grams, and collocations are examined through AntConc and, where necessary, basic Python-based techniques. Subsequently, selected patterns are interpreted in their contexts to identify their functions. The findings show that academic writing contains frequent recurring patterns that perform important communicative roles. These patterns help writers connect ideas, present evidence, develop arguments, express evaluation and certainty, and construct an academic voice. Moreover, the findings indicate that frequency alone cannot explain the importance of a linguistic pattern; its context and function must also be considered. Therefore, the study concludes that frequency and function are closely connected in academic writing. In addition, combining quantitative corpus analysis with contextual interpretation provides a fuller understanding of academic language. Finally, corpus-informed teaching is recommended to help learners understand not only frequent words but also how recurring patterns are used effectively in academic contexts.
