From Latin 'bilix' (two-threaded), Germanicized from 'bi-' to 'tw-'—the weave uses two thread directions.
A type of textile weave with a pattern of diagonal parallel ribs, producing a sturdy, draping fabric.
From Old English 'twili' (woven with a double thread), from Latin 'bilix' (two-threaded), from 'bi-' (two) + 'licium' (thread). The initial 'tw-' is a Germanic substitution for Latin 'bi-,' both meaning 'two.' Key roots: bi- (Latin: "two"), licium (Latin: "thread").
