What's the difference between i.e. and e.g.?
c.1200, "religious musing," from Old French contemplation or directly from Latin contemplationem (nominative contemplatio) "act of looking at," from contemplat-, past participle stem of contemplari "to gaze attentively, observe," originally "to mark out a space for observation" (as an augur does). From com-, intensive prefix (see com-), + templum "area for the taking of auguries" (see temple (n.1)).
