Abstract

Expressions in which the word for a body part is also used for objects can be found in many languages. Some languages use body part terms to refer to object parts, while others have only a few idiosyncratic examples in their vocabulary. Studying the word forms referring to body and object concepts, i.e., colexifications, across languages, offers insights into cognitive principles facilitating such usage. Previous studies focused on full colexifications in which the same word form expresses two distinct concepts. Here, we utilize a new approach that allows us to analyze partial colexifications in which a concept is built out of the word forms for two separate concepts, like river mouth. Based on a large lexical database, we identified body and object concepts and analyzed 39 colexifications across 329 languages. The results show that word forms for body concepts are used slightly more frequently as a source for object names. However, the detailed examination of directional tendencies and colexifications of word forms between body and object concepts reveals linguistic variation. The study sheds light on meaning extensions between two concrete domains and showcases the synergies that arise through the combination of existing data and methods
