Constructing Nature through Language: A Corpus-Based Comparative Analysis of Written and Spoken Discourse on Penguins

Abstract

This study presents a corpus-based comparative analysis of written and spoken discourse on penguins to investigate how language constructs representations of marine wildlife across modalities. Drawing on seven books (written corpus) and twenty-nine documentary transcripts from multiple channels (spoken corpus), the research adopts a mixed-method approach combining quantitative frequency analysis with qualitative interpretation. The findings reveal significant register variation between written and spoken data. The written corpus demonstrates high lexical density, with frequent use of content nouns such as penguin, species, population, colonies, and Antarctic, reflecting scientific classification and ecological orientation. Verbs such as breeding, hatching, and monitoring emphasize biological processes, while technical adjectives such as genetic and non-breeding indicate descriptive precision. In contrast, the spoken corpus features more dynamic verbs including hunt, swim, fight, and grow, highlighting movement and survival. Adjectives such as cold, giant, hungry, and wild contribute to emotional engagement and narrative dramatization. The unexpected prominence of words like music further reflects documentary production elements. Overall, written discourse constructs penguins as ecological and scientific entities, whereas spoken discourse frames them within action-driven survival narratives. The study contributes to corpus linguistics, register analysis, and ecolinguistics by demonstrating how linguistic patterns shape public understanding of wildlife across genres and modalities.
