The Mouton World Atlas of Variation in English (WAVE) presents grammatical variation in
spontaneous spoken English  mapping 235 features in 48 varieties of English (traditional
dialects  high-contact mother tongue Englishes  and indiginized second-language Englishes) and
26 English-based Pidgins and Creoles in eight Anglophone world regions (Africa  Asia  Australia
British Isles  the Caribbean  North America  the Pacific  and the South Atlantic). The analyses
of the 74 varieties are based on descriptive materials  naturalistic corpus data  and native
speaker knowledge.
