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.

also archi-, word-forming element meaning “chief, principal; extreme, ultra; early, primitive,” from Latinized form of Greek arkh-, arkhi- “first, chief, primeval,” comb. form of arkhos “chief” (see archon).

word-forming element meaning “a ruler,” from Greek arkhos “leader, chief, ruler,” from arkhe “beginning, origin, first place” (see archon).

arch (ärch)
n.
An organ or structure having a curved or bowlike appearance, especially either of two arched sections of the bony structure of the foot.

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

Note: The form of arch used in building often serves to distinguish styles of architecture from one another. For example, Romanesque architecture usually employs a round arch, and Gothic architecture, a pointed arch.

archbishop

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.)
