What's the difference between i.e. and e.g.?
"raised turret atop a house," 1590s, from Italian belvedere, literally "a fair sight," from bel, bello "beautiful" (from Latin bellus "beautiful, fair;" see bene-) + vedere "a view, sight" (see vista). Pronunciation perhaps influenced by the French form of the word. So called because it was used for viewing the grounds.
