thong: [OE] Etymologically, a thong is something that ‘binds’ up. The word comes from a prehistoric Germanic *thwangg-, which also produced German zwang ‘constraint’. In the Old English period it was thwong; it began to lose its w in the 13th century.
thong (n.)
Old English twong, twang "narrow strip of leather" (used as a cord, band, strip, etc.), from Proto-Germanic *thwang- (cognates: Old Norse tvengr), from PIE root *twengh- "to press in on, to restrain" (cognates: Old English twengan "to pinch, squeeze"). As a kind of sandal, first attested 1965; as a kind of bikini briefs, 1990.
