In his study Postcolonial English: Varieties around the World (2007), Edgar Schneider proposes a sociolinguistic and contact-linguistic ‘Dynamic Model’ to account for the emergence of new varieties. He goes on to demonstrate this Dynamic Model in sixteen case studies, covering four continents and spanning the entire functional range from L1 Englishes spoken by descendants of European settler-colonists, through L2 varieties serving as languages of education and administration, to new varieties developing in contact with English-lexifier pidgins and creoles.
