What's the difference between i.e. and e.g.?
early 13c., from Old French haste "haste, urgency, hastiness" (12c., Modern French hâte), from Frankish *haifst "violence," from West Germanic *haifstiz (cf. Gothic haifsts "strife," Old English hæste "violent, vehement, impetuous"). To make haste is recorded by 1530s.
late 13c., from Old French haster (Modern French hâter), from haste (see haste). Now largely superseded by hasten (1560s).
