occur: occur: [16] Etymologically, occur means ‘run towards’. It was borrowed from Latin occurrere, a compound verb formed from the prefix ob- ‘towards’ and currere ‘run’ (source of English course, current, etc). This had the sense ‘run to meet’, hence simply ‘meet’, which survived into English: ‘The whole multitude might freely move … with very little occurring or interfering’, Richard Bentley, Boyle Lectures 1692. But ‘meeting’ also passed into ‘presenting itself’, ‘appearing’, and hence ‘happening’ – from which the main present-day meaning of English occur comes.
=> course, current
occur (v.): 1520s, "meet, meet in argument," from Middle French occurrer "happen unexpectedly" or directly from Latin occurrere "run to meet, run against, befall, present itself," from ob "against, toward" (see ob-) + currere "to run" (see current (adj.)). Sense development is from "meet" to "present itself" to "appear" to "happen" ("present itself in the course of events"). Meaning "to come into one's mind" is from 1620s. Related: Occurred; occurring.
