1660s, an old chemistry term for "minerals which were readily fusible and useful as fluxes in smelting" [Flood], from Latin fluor, originally meaning "a flowing, flow," from fluere "to flow, stream, run, melt" (see fluent). Said to be from a translation of the German miners' name, flusse. Since 1771 applied to minerals containing fluorine, especially calcium fluoride (fluorspar or fluorite).ETD fluor (n.).2
1853 (Stokes), from fluor- (see fluoro-) + -escent. Also see fluorescence. The electric fluorescent lamp was invented by Edison in 1896, but such lights were rare in homes before improved bulbs became available in the mid-1930s.ETD fluorescent (adj.).2
1866 (implied in fluoresced), back-formation from fluorescence. Related: Fluorescing.ETD fluoresce (v.).2
1852, "property of glowing in ultraviolet light," coined by English mathematician and physicist Sir George G. Stokes (1819-1903) from fluorspar (see fluorine), because in it he first noticed the phenomenon, + -escence, on analogy of phosphorescence.ETD fluorescence (n.).2
"compound of fluorine with another element," 1826, from fluorine + -ide.ETD fluoride (n.).2
1949, back-formation from fluoridation. Related: Fluoridated; fluoridating.ETD fluoridate (v.).2
1904, "process of absorbing fluoride," from fluoride + -ation. In reference to adding traces of fluoride to drinking water as a public health policy, from 1949.ETD fluoridation (n.).2
non-metallic element, 1813, coined by English chemist Sir Humphry Davy from fluorspar ("calcium fluoride," modern fluorite), the late 18c. name of the mineral where it was first found (see fluor) + chemical suffix -ine (2). Not isolated until 1886. Related: Fluorinate; fluorination.ETD fluorine (n.).2
before vowels fluor-, combining form of fluorine; also see fluorescence.ETD fluoro-.2
1937, from fluoro- + carbon.ETD fluorocarbon (n.).2
1896, from fluoroscope (1896) "device for observing x-rays by means of action in fluorescent substances," from fluoro- + -scope. Related: Fluoroscopic.ETD fluoroscopy (n.).2
1757, "produce agitation of feeling in, confuse by excitement," from flurry (n.). From 1883 of snow. Related: Flurried; flurries; flurrying.ETD flurry (v.).2
