What's the difference between i.e. and e.g.?
early 15c., "develop, proceed, extend," from Latin producere "lead or bring forth, draw out," figuratively "to promote, empower; stretch out, extend," from pro- "forth" (see pro-) + ducere "to bring, lead" (see duke). Sense of "bring into being" is first recorded 1510s; that of "put (a play) on stage" is from 1580s. Related: Produced; producing.
"thing or things produced," 1690s, from produce (v.), and originally accented like it. Specific sense of "agricultural productions" (as distinguished from manufactured goods) is from 1745.
