Word Origin and History for arching

arch

n.

c.1300, from Old French arche "arch of a bridge" (12c.), from Latin arcus "a bow" (see arc). Replaced native bow (n.1). Originally architectural in English; transferred by early 15c. to anything having this form (eyebrows, etc.).

adj.

1540s, "chief, principal," from prefix arch-; used in 12c. archangel, etc., but extended to so many derogatory uses (arch-rogue, arch-knave, etc.) that by mid-17c. it acquired a meaning of "roguish, mischievous," since softened to "saucy." Also found in archwife (late 14c.), variously defined as "a wife of a superior order" or "a dominating woman, virago."

v.

early 14c., "to form an arch" (implied in arched); c.1400, "to furnish with an arch," from arch (n.). Related: Arching.

In architecture, a curved or pointed opening that spans a doorway, window, or other space.

arching in the Bible

an architectural term found only in Ezek. 40:16, 21, 22, 26, 29. There is no absolute proof that the Israelites employed arches in their buildings. The arch was employed in the building of the pyramids of Egypt. The oldest existing arch is at Thebes, and bears the date B.C. 1350. There are also still found the remains of an arch, known as Robinson's Arch, of the bridge connecting Zion and Moriah. (See TYROPOEON VALLEY.)
