This is the very first publication mapping onomatopoeia in the languages of the world. The publication provides a comprehensive, multi-level description of onomatopoeia in the world’s languages. The sample covers six macro-areas defined in the WALS: Euroasia, Africa, South America, North America, Australia, Papunesia. Each language-descriptive chapter specifies phonological, morphological, word-formation, semantic, and syntactic properties of onomatopoeia in the particular language. Furthermore, it provides information about the approach to onomatopoeia in individual linguistic traditions, the sources of data on onomatopoeia, the place and the function of onomatopoeia in the system of each language.
