dry: [OE] Dry comes ultimately from prehistoric Germanic *draugiz, a derivative of the base *draug-, *drūg-, which also produced English drought and drain. Its other Germanic relatives are Dutch droog and German trocken, and some have connected it with Old Norse drjūgr ‘lasting, strong’, Old Prussian drūktai ‘firmly’, and Lithuanian dialect drūktas ‘thick, strong’ – the theory being that strength and endurance are linked with ‘drying out’. => drain, drought
