Where it comes from
The verb is derived from Middle English outgon (“to go out, depart, leave; to come out, emerge; to escape; to protrude; of a sword: to be drawn; to emanate from (a place); to accompany”), from Old English ūtgān (“to go out”), Proto-West Germanic *ūtgān (“to go out”), equivalent to out- + go. See also go out. Compare Middle English outwenden (“to go out, depart, leave; to escape; to be emitted, fly out from; of a weapon: to be drawn”), which, like modern outgo, had the past tense and past participle form outwent. The noun is derived from modern English out- (prefix meaning ‘away from; toward the outside of’) + go. Sense 1 (“cost, expenditure, or outlay”) was probably modelled on income. Cognates * Scots outgae * West Frisian útgean * Dutch uitgaan * German Low German utgahn * German ausgehen * Swedish utgå
