What's the difference between i.e. and e.g.?
late 14c., cicoree (modern form from mid-15c.), from Middle French cichorée "endive, chicory" (15c., Modern French chicorée), from Latin cichoreum, from Greek kikhorion (plural kikhoreia) "endive," of unknown origin. Klein suggests a connection with Old Egyptian keksher. The modern English form is from French influence.
