Where it comes from
The verb is derived from Middle English oversetten (“to place or set over, cover; to assail; to defeat, overcome, overpower, overthrow; to defer; to discredit, refute; to disregard, overlook, set aside; to hinder; to oppress; to repulse”), from Old English ofersettan (“to put in a position of authority; to overcome or be overcome; to set over”), from Proto-West Germanic *ubarsattjan (“to place above, set over; to establish, install”), from *ubarsittjan (“to abstain from, neglect; to occupy, possess; to sit over or upon”), from *ubar- (prefix meaning ‘above, over’) + *sittjan (“to sit”) (from Proto-Germanic *sitjaną (“to sit”), ultimately from Proto-Indo-European *sed- (“to sit”)). By surface analysis, over- (prefix meaning ‘above, higher; excessive, excessively’) + set (verb). Doublet of oversit. Verb sense 1.2.3 (“to translate (a text)”) is probably a calque of German übersetzen.
