betwixt

From Middle English bitwixe, from Old English betweox, from Proto-Germanic *twiskaz (“twofold, double”), from Proto-Indo-European *dwís (“twice, doubly; in two”). By surface analysis, be- (“by, near, around”) + twixt (“between”). Compare Saterland Frisian twiske (“between”), Dutch tussen, German zwischen.
