eWAVE: the electronic World Atlas of Varieties of English
eWAVE is an interactive database on morphosyntactic variation in spontaneous spoken English mapping 235 features from a dozen domains of grammar in now 50 varieties of English (traditional dialects, high-contact mother-tongue Englishes, and indigenized second-language Englishes) and 26 English-based Pidgins and Creoles in eight Anglophone world regions (Africa, Asia, Australia, British Isles, Caribbean, North America, Pacific, and the South Atlantic; see here for a list). It was compiled from descriptive materials, naturalistic corpus data, and native speaker knowledge by a team of 83 contributors, all leading experts in their fields, directed by Bernd Kortmann and Kerstin Lunkenheimer. eWAVE is unique not only in its coverage and user-friendliness, but also in being an open access resource. As such it has the potential for serving both as a teaching tool in academic teaching around the world and as an indispensable research tool for specialists in many different fields of linguistics, including creolistics, dialectology, dialect syntax, language change, language typology, sociolinguistics, second language acquisition, and the study of World Englishes and learner Englishes.
