occupy

History and Etymology for occupy

Middle English occupien "to take possession of, hold, inhabit, take up space in, fill, keep (oneself) busy," borrowed from Anglo-French occuper, occupier, borrowed from Latin occupāre "to grasp, appropriate to oneself, take possession of, fill up (space, a position), forestall," from oc-, assimilated variant of ob- ob- + -cupāre, intensive derivative of capere "to take, seize, catch" — more at heave entry 1

Note: The source of the -i- in Anglo-French occupier and Middle English occupien, retained in Modern English, is unclear, as continental French has only occuper. The verb occupy, common in later Middle and early Modern English, was very infrequently used in the 17th and first two thirds of the 18th century; it has been suggested that this was due to the sense "to have sexual intercourse with (a woman)," which impinged by connotation on the less charged meanings and led to a taboo on any use of the word. When the socially unacceptable sense fell out of circulation occupy once more became a generally used word.
