Logeme is a widely used concept in studies of the unit of translation. But the derivation of this word in western translatoloty needs to be further explored, and the concept itself also demands more clarification. In addition, the adoption and inheritance of this notion inside and outside of China (especially the former) are hardly satisfactory. This paper scrutinizes and discusses the abovementioned questions, based on which it then argues that the unit of translation should essentially be the unit of analysis in translation. As the unit of transfer in translation, its practicability is difficult to demonstrate.
