What's the difference between i.e. and e.g.?
1727, a physician's term for "condition of feeling healthy and comfortable (especially when sick)," medical Latin, from Greek euphoria "power of enduring easily," from euphoros, literally "bearing well," from eu "well" (see eu-) + pherein "to carry" (see infer). Non-technical use, now the main one, dates to 1882 and is perhaps a reintroduction.
euphoria eu·pho·ri·a (yōō-fôr'ē-ə)
A feeling of great happiness or well-being, commonly exaggerated and not necessarily well founded.
