This handbook provides a comprehensive and thorough survey of our current insights into the diversity and unity found across the 6000 languages of this planet. The 125 articles include inter alia chapters on the patterns and limits of variation manifested by analogous structures, constructions and linguistic devices across languages (e.g. word order, tense and aspect, inflection, color terms and syllable structure). Other chapters cover the history, methodology and the theory of typology, as well as the relationship between language typology and other disciplines.

The authors of the individual sections and chapters are for the most part internationally known experts on the relevant topics. The vast majority of the articles are written in English, some in French or German. The handbook is not only intended for the expert in the fields of typology and language universals, but for all of those interested in linguistics. It is specifically addressed to all those who specialize in individual languages, providing basic orientation for their analysis and placing each language within the space of what is possible and common in the languages of the world.
