Explicitation constitutes a focal point within the realm of interpretation studies. It embodies a process whereby expressions originating from the source language are rephrased into clearer and more comprehensible renditions, harmonizing with the linguistic norms and practices of the target language. The process of explicitation involves not only the conversion of languages but also a deep understanding of cultural backgrounds and context. Explicitation goes beyond mere language conversion, effective explicitation enhances the precision and subtlety of meaning transfer in interpreting. Most of the research on explicitation in the academic circle focuses on translation. This paper endeavors to furnish a thorough examination of explicitation research through a multifaceted lens, encompassing the delineation of explicitation, its classification, as well as both domestic and international scholarship pertaining to explicitation, alongside an exploration of the underlying rationales. Its primary objective is to serve as a scholarly resource for forthcoming investigations into the phenomena of explicitation in interpretation, thus stimulating translators within our jurisdiction to assume a more pronounced role in this domain and actively participate in discourses on explicitation research within the global translation community.
