英语词汇glaucoma的起源、历史背景-英语词源词典

词汇	glaucoma
词源	glaucoma n. 1640s (cataracts and glaucoma not distinguished until c. 1705), from Latinized form of Greek glaukoma "cataract, opacity of the lens," perhaps from glaukommatos "gray-eyed," with omma "the eye" + glaukos, an adjective of uncertain origin (see glaucous). Entries linking to glaucoma glaucous adj. "dull bluish-green, gray," 1670s, from Latin glaucus "bright, sparkling, gleaming," also "bluish-green," from Greek glaukos, a word used in Homer of the sea as "gleaming, silvery" (apparently without a color connotation); used by later writers with a sense of "greenish" (of olive leaves) and "blue, gray" (of eyes). Beekes says it is probably a substratum word from Pre-Greek. Homer's glauk-opis Athene probably originally was a "bright-eyed," not a "gray-eyed" goddess. Greek for "owl" was glaux, perhaps from its bright, staring eyes, but this, too, might be an unrelated Pre-Greek word. Middle English had glauk "bluish-green, gray" (early 15c.). updated on March 10, 2015
