In Corpus Linguistics and Sociolinguistics, Beke Hansen analyses variation and change in the modal systems of three second-language varieties of English in Asia by taking a sociolinguistic approach to corpus data. Her study focuses on the modal and semi-modal verbs of strong obligation and necessity in Hong Kong English, Indian English, and Singapore English based on the relevant ICE component corpora. She adopts a typologically-informed perspective on variation in World Englishes by comparing the structures of the speakers’ first languages with the structures of the emergent varieties in the expression of epistemic modality. Beyond this, she analyses language change by constructing apparent-time scenarios to compensate for the lack of diachronic corpora in World Englishes.
