fem. proper name, Old English Eadgyð, from ead "riches, prosperity, good fortune, happiness" + guð "war." A fairly common name; it survived through the Middle Ages, probably on the popularity of St. Eadgyð of Wilton (962-84, abbess, daughter of King Edgar of England), fell from favor 16c., was revived in fashion late 19c. Old English ead (also in eadig "wealthy, prosperous, fortunate, happy, blessed; perfect;" eadnes "inner peace, ease, joy, prosperity") became Middle English edy, eadi "rich, wealthy; costly, expensive; happy, blessed," but was ousted by happy. Late Old English, in its grab-bag of alliterative pairings, had edye men and arme "rich men and poor."
Trojan youth taken by Zeus as his cup-bearer (and lover), from Greek Ganymedes, perhaps a non-Greek name, or from ganymai "I rejoice, am glad" (related to ganos "brightness; sheen; gladness, joy; pride") + medea (plural) "counsels, plans, cunning" (see Medea); taken in Greek folk-etymology to mean "delighting in genitals."
Used figuratively of serving-boys (c. 1600) and catamites (1590s). Associated with Aquarius in the zodiac. As the name of one of the four large satellites of Jupiter, proposed in Latin 1610s, but not widely used before 1847.
