tangent
English
editEtymology
editBorrowed 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.
Pronunciation
editNoun
edittangent (plural tangents)
- (differential geometry) A straight line touching a curve at a single point without crossing it there.
- 1951 May, “British Railways Standard Coaches”, in Railway Magazine, page 327:
- One feature of the body, which is constructed of pressed-steel members, is the contour of the sides. They are in the form of a continuous radius from the bottom side to the cant rail, and to enable flat glass windows to be fitted the side panels are pressed around the window opening, forming a tangent to the curved bodyside.
- Synonym: tangent line
- (mathematics) A function of an angle that gives the ratio of the sine to the cosine, in either the real or complex numbers. Symbols: tan, tg.
- A topic nearly unrelated to the main topic, but having a point in common with it.

- “Uncle Barnaby was always father and mother to me,” Benson broke in; then after a pause his mind flew off at a tangent. “Is old Hannah all right—in the will, I mean?”
- 2009: Stuart Heritage, Hecklerspray, Friday the 22nd of May in 2009 at 1 o’clock p.m., “Jon & Kate Latest: People You Don’t Know Do Crap You Don’t Care About”
- Jon & Kate Plus 8 is a show based on two facts: (1) Jon and Kate Gosselin have eight children, and (2) the word ‘Kate’ rhymes with the word ‘eight’. One suspects that if Kate were ever to have another child, a shady network executive would urge her to put it in a binbag with a brick and drop it down a well. But this is just a horrifying tangent.
- (art) A visual interaction between two or more lines or edges that creates a perceived relationship between them, often in a way that the artist did not intend.
- (music) A small metal blade in a clavichord that strikes the strings to produce sound.
