Etymology[edit]

From Latin tangentem, the accusative of tangēns(touching) (in the phrase līnea tangēns(a touching line)), the present participle of the verb tangō(touch, verb), from Proto-Indo-European *tag-, *taǵ-(to touch). Cognate with Old English þaccian(to touch lightly, pat, stroke). More at thack, thwack.
