This chapter explores terminological variation as an inherent characteristic of financial discourse, with a focus on its implications for financial translation. Moving beyond isolated terms, it considers the broader textual and contextual environments in which terminology occurs across diverse financial documents. Being grounded in contemporary theories of terminology, such as Communicative Theory, Sociocognitive Terminology, and Frame-Based Terminology, the paper examines the increasing diversity of financial terminology, its underlying causes, and its impact on translation quality. The chapter ultimately emphasises the need for context-aware translation strategies in navigating the complexities of financial language.
