etymonline
arbitrary (adj.)
c. 1400, "deciding by one's own discretion, depending on one's judgment," from Latin arbitrarius "of arbitration," hence "depending on the will, uncertain," from arbiter (see arbiter). The meaning in English gradually descended to "capricious, ungoverned by reason or rule, despotic" (1640s). Related: Arbitrarily; arbitrariness.
