Creative Constructions In Asian And World Englishes - And What They Teach Us, Edgar W. Schneider Jun 2026

Creative Constructions In Asian And World Englishes - And What They Teach Us, Edgar W. Schneider

Journal of English and Applied Linguistics

"Creative constructions" are defined as patterns which deviate slightly but noticeably from grammatical, fully licensed structures in English (and are therefore sometimes branded as "wrong"), inviting specific cognitive associations to make sense of them. It is argued that such structures offer a window into the nature of the cognitive manipulation of linguistic innovations and change. The concept is related to creativity in literature and lingua franca English, and it is surveyed theoretically by asking how established grammatical theories (like traditional grammar, structuralism or generativism) or more recent approaches to the nature of grammar (usage-based linguistics, construction grammar, and complex systems …
