1
First recorded in 1350–1400; Middle English verb venten “to furnish (a vessel) with a vent,” by shortening of Old French esventer (equivalent to es- + -venter, verbal derivative of vent, from Latin ventus “wind”), in later use derivative of the English noun; noun partly from French vent, partly by shortening of French évent (Old French esvent, derivative of esventer ), and partly derivative of the English verb; see ex-1, wind1
