What's the difference between i.e. and e.g.?
c.1300, bordel "house of prostitution," from Old French bordel "small hut, cabin; brothel" (12c.), diminutive of borde "hut made of planks," from Frankish *bord "wooden board" or some other Germanic source related to board (n.1). The modern form is a result of the French word being borrowed by Italian then passed back to French with a suffix and re-borrowed into English in its current form by 1590s.
