单词 cataract
释义

cataractn.

Brit. /ˈkatərakt/, U.S. /ˈkædəˌræk(t)/
Forms: Middle English cataracte, ( cateracte, catterak, 1500s catracte, catharact, catarrhacte, 1500s–1600s catarract(e, 1600s cattaract, chateract, 1700s catarect, 1500s– catarack), 1600s caterick, 1600s– cataract.
Etymology: < French cataracte (in senses 1 4, 6), < Latin cataracta waterfall, portcullis, floodgate, < Greek καταρ(ρ)άκτης down-rushing, a down rushing bird, a portcullis, waterfall, ? (in the Septuagint) floodgate; < καταράσσειν to dash down, dash headlong, rush or fall headlong, as rain or a river, < κατ' or κατά down + ἀράσσειν or ῥάσσειν to dash. (But some think it a derivative of καταρρηγνύναι to break down.) The sense-development in Greek, Latin, and French-English, is not in all respects clear.
1.
a. plural. The ‘flood-gates’ of heaven, viewed as keeping back the rain (with reference to Genesis vii. 11, viii. 2, where Hebrew has 'rbt lattices, windows, Septuagint καταρράκται, Vulgate cataractæ, the former probably, the latter certainly, = flood-gates, sluices; hence also French cataractes du ciel). This, the earliest use in English, is now Obsolete.

4. Pathology. An opacity of the crystalline lens of the eye, or of the capsule of the lens, or of both, ‘producing more or less impairment of sight, but never complete blindness’ ( New Sydenham Soc. Lexicon).[Apparently a figurative use of the sense portcullis. In French, the physician A. Paré (c1550) has ‘cataracte ou coulisse’; and Cotgrave (1611) has coulisse ‘a portcullis.. also a web in the eye’, the notion being that even when the eye is open, the cataract obstructs vision, as the portcullis does a gateway. (But if originally in medieval Latin, it might arise from the sense ‘window-grating’ fenestra clathrata, Du Cange.)]
