arch-
1| a combining form that represents the outcome of archi- in words borrowed through Latin from Greek in the Old English period; it subsequently became a productive form added to nouns of any origin, which thus denote individuals or institutions directing or having authority over others of their class (archbishop; archdiocese; archpriest). More recently, arch-1 has developed the senses “principal” (archenemy; archrival) or “prototypical” and thus exemplary or extreme (archconservative); nouns so formed are almost always pejorative. |
-arch
| a combining form meaning “chief, leader, ruler,” used in the formation of compound words: monarch; matriarch; heresiarch. |

Arch
Arch\, n. [F. arche, fr. LL. arca, for arcus. See Arc.]1. (Geom.) Any part of a curved line. 2. (Arch.) (a) Usually a curved member made up of separate wedge-shaped solids, with the joints between them disposed in the direction of the radii of the curve; used to support the wall or other weight above an opening. In this sense arches are segmental, round (i. e., semicircular), or pointed. (b) A flat arch is a member constructed of stones cut into wedges or other shapes so as to support each other without rising in a curve. Note: Scientifically considered, the arch is a means of spanning an opening by resolving vertical pressure into horizontal or diagonal thrust. 3. Any place covered by an arch; an archway; as, to pass into the arch of a bridge. 4. Any curvature in the form of an arch; as, the arch of the aorta. "Colors of the showery arch." --Milton.

arch

Arch
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.)
