Origin
- Proto-Indo-European*teh₂g-
- Proto-Italic*tangō
- Latintangō
- Latintangēns
- Latintangentem
- Englishtangent
Borrowed 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-Italic *tangō, from Proto-Indo-European *teh₂g- (“to touch”). Cognate with Old English þaccian (“to touch lightly, pat, stroke”). More at thack, thwack.
