From Middle English tough, towgh, tou, toȝ, from Old English tōh (“tough, tenacious, holding fast together; pliant; sticky, glutinous, clammy”), from Proto-West Germanic tą̄h(ī), from Proto-Germanic tanhuz (“fitting; clinging; tenacious; tough”), from Proto-Indo-European *denḱ- (“to bite”). Cognates Cognate with Saterland Frisian toai, Low German tei, tah, tage, Dutch taai, Luxembourgish zéi, German zäh(e), Bavarian zaach, all principally “chewy, leathery, sticky”, and hence “tenacious, resilient, dogged”.
