Interjections and ideophones are minor classes of invariable words that often display phonosymbolism, thereby being on the crossroads between arbitrary and motivated language. In the history of linguistic description, these words have been the object of major difficulties of definition. Starting out with case studies, the project analyzes the morphological, syntactic and semantic properties of these word classes by combining the perspectives of linguistic typology, diachrony, areal linguistics, and the analysis of multimodal speech.
