A Språkforum talk by Marcelle Cole, Assistant Professor in English Historical Linguistics and Medieval Literature at the University of Utrecht.

Abstract
This talk challenges the long-held theory that the English pronouns they, their, them are loanwords from Old Norse, arguing instead that the pronouns ultimately derive from the Old English demonstratives þā – þāra – þām. Based on quantitative and qualitative analysis of third-person plural personal pronoun usage in early English, I present evidence of morphosyntactic and phonological continuity from Old to Middle English, particularly in the northern and (south)western dialects. I explore the idea that contact with Old Norse primarily reinforced existing native developments rather than introducing entirely new forms, thus highlighting the complex interplay of internal linguistic evolution and language contact that combined to shape they, their, them.
