ion
1834, introduced by Eng. physicist and chemist Michael Faraday (suggested by the Rev. William Whewell, Eng. polymath), coined from Gk. ion, neut. prp. of ienai "go," from PIE base *ei- "to go, to walk" (cf. Gk. eimi "I go;" L. ire "to go," iter "a way;" O.Ir. ethaim "I go;" Ir. bothar "a road" (from
EXPAND
*bou-itro- "cows' way"), Gaulish eimu "we go," Goth. iddja "went," Skt. e'ti "goes," imas "we go," ayanam "a going, way;" Avestan ae'iti "goes;" O.Pers. aitiy "goes;" Lith. eiti "to go;" O.C.S. iti "go;" Bulgarian ida "I go;" Rus. idti "to go"). So called because ions move toward the electrode of opposite charge. Ionosphere coined 1926 by R.A. Watson-Watt.
