This introductory chapter establishes the foundational concepts of translator style, encompassing various interpretations from Baker’s “thumbprints” to Saldanha’s distinction between translator and translational style. It explains the significance of studying translator style for understanding translators as active agents, the interplay between source and target texts, and translation theory development. The chapter introduces corpus stylistics as a means to bridge the gap between formal linguistic analysis and functional literary appreciation in translator style research, setting the stage for the book’s exploration of functional style through corpus stylistic methods.
