Word Origin & History

arch
c.1300, from O.Fr. arche "arch of a bridge," from L. arcus (see arc). Replaced native bow (n.1). Transferred by 1590 to anything having this form (eyebrows, etc.). The verb meaning "to curve" is from 1620s. Related: Archway (1802).

arch
1540s, "chief, principal," from prefix arch- (from Gk. arkhos "chief;" see archon); used in 12c. archangel, etc., but extended to so many derogatory uses (arch-rogue, arch-knave, etc.) that it acquired a meaning of "roguish, mischievous," since softened to "saucy" (1660s).
Also found in archwife (late 14c.) "A wife of a superior order."

arch definition


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

Arch definition


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.)
