Etymology

It is inherited from Middle English arbitour, also arbitre,[2][3][4] borrowed from Old French arbitre (“arbiter, judge”)[5][6][3][7] and directly borrowed from Latin arbiter (“eye-witness; judge”).[5][7][8] The OED notes that arbitrour came first in English, then arbitrator, and that the Latin form arbiter followed in the 16th century, though arbitre may well have existed in Middle English.[8] The Anglo-Norman arbitre is recorded from about 1270.[9] The further origin of the Latin noun is disputed.[6][10] The usual explanation takes it from ad (“to”) and baetō (“to go”), so "one who goes to see or to examine",[5][3][8][7] and de Vaan calls that verb the only straightforward formal connection, though the verb itself has no certain etymology.[10] He compares Umbrian ařputrati (“according to the judgement”).[10][3] The American Heritage Dictionary instead assumes a Phoenician origin,[6] and Collins calls its origin obscure.[11]

Earliest recorded meaning

A person chosen to settle a dispute, as arbitour in the C text of Piers Plowman, before 1387.[2][7] Etymonline dates the noun to the late 14th century,[5] and the OED's first record of the spelling arbiter is from about 1503, in Richard Arnold's Chronicle.[8] The feminine arbitress is recorded even earlier, in the mid-14th century.[5]

Semantic evolution

In classical Latin the arbiter could simply be a spectator or eye-witness, and in law the person who heard and decided a case.[5][10] The English word has only the judging senses,[2][8] and its Anglo-Norman source already meant an arbitrator.[9] The specific sense of a person chosen by two disputing parties is dated to 1548 by the OED,[8][5] and it passed quickly into figurative use, as in Milton's twilight, "short Arbiter 'Twixt Day and Night".[12] The sense of someone who decides by sole will or pleasure follows in 1628,[8] and Johnson (1755) gives both senses, a judge the parties submit to and one who has the power of decision.[13] Weekley notes that the modern sense of arbitrary evolved from the full powers granted to an arbiter.[14] The phrase arbiter elegantiae, or arbiter elegantiarum, a judge of taste, goes back to Tacitus's description of Petronius at Nero's court, punning on his surname Arbiter, and is recorded in English from 1818.[8][5]
