Forms

arc n (plural arcuri)[1] The plural is arcuri;[2][3] arce is used for the arc of a curve, and old texts use it for bows as well.[2][3]

Etymology

It is inherited from Latin arcus (“bow, arch”), a word continued across the Romance languages.[4][3][5][1] The Latin word goes back to Proto-Indo-European *h₂erkʷo- (“bow, arrow”).[1] De Vaan compares Germanic words for “arrow”, such as Old English earh, and Proto-Slavic *orkyta (“willow”).[6]

The word survives south of the Danube: Aromanian arcu and Megleno-Romanian arc, the bow of the cotton carder.[4][7][8] Its Romance relatives include Italian arco, Occitan arc, Spanish arco and Portuguese arco.[3][5] The senses of mathematics, architecture and engineering came from French arc.[4]

Earliest recorded meaning

DELR dates the first record to the Psaltirea Hurmuzaki (c. 1500–1520), where the forms arcul and arcele name the weapon.[4][9] Coresi's Psalter has „că, adecă, păcătoșii întinseră arcul” “for lo, the sinners have bent the bow”.[10][11] MDA2 cites the same psalter through Hasdeu.[12]

Semantic evolution

The bow was the first sense, and anything bent in its shape could be called arc: arcul sprâncenei “the arch of the eyebrow”.[2][4] The vault of a building, the triumphal arch, the arc of a circle and the spring of a carriage or a lock followed, partly after French usage.[4][13][2] In Oltenia and the Banat the word is also the bow of a stringed instrument, and Tiktin records it as the crown set on the heads of bride and groom at a wedding.[14]

Tiktin calls the phrase a avea mai multe coarde la arc “to have more strings to one's bow” a Gallicism.[14] Physics and physiology added the electric arc and the reflex arc.[2] In the press of the 1990s arcul guvernamental was the group of parties supporting the government.[15]

Old derivatives are arcaș “archer” (c. 1650), arcar “bowyer” (c. 1690) and arcuș “bow of a violin” (1691–1697).[4][3]
