Forms

horizontal (feminine horizontale, masculine plural horizontaux, feminine plural horizontales)[1] First written orizontal (1545); the spelling horizontal is recorded in 1636 by Monet.[2][3]

Etymology

It is formed from French horizon + -al, built on the stem of the noun's Latin genitive.[4][5] The Grand Robert derives it from orizonte, the old form of the noun.[3] The noun itself is from Latin horizon, from Ancient Greek ὁρίζων (horízōn), the present participle of a verb meaning “to bound, limit”.[5][1]

Earliest recorded meaning

It is first found in 1545 in lignes horizontales “horizontal lines”, in Jean Martin's French translation of Sebastiano Serlio.[4][6]

Semantic evolution

The adjective first described what is parallel to the astronomical horizon.[6] Furetière recorded it in 1690 for the lying position, and the Académie had se mettre dans la position horizontale “to lie down” in 1835.[2] The feminine horizontale became a noun for the horizontal position (1690) and a horizontal straight line.[6]

In slang of 1881, by allusion to lying down, une horizontale meant a prostitute; this use has nearly disappeared.[6][5] In the 20th century the word took a figurative sense, of what joins people or things on the same level (opposed to vertical), as in concentration horizontale for the merger of firms.[6] Within a firm or an institution it is found in 1964.[7]
