Vision

From www.etymonline.com: c.1290, "something seen in the imagination or in the supernatural," from Anglo-Fr. visioun, O.Fr. vision, from L. visionem (nom. visio) "act of seeing, sight, thing seen," from pp. stem of videre "to see," from PIE base *weid- "to know, to see" (cf. Skt. veda "I know;" Avestan vaeda "I know;" Gk. oida, Doric woida "I know," idein "to see;" O.Ir. fis "vision," find "white," i.e. "clearly seen," fiuss "knowledge;" Welsh gwyn, Gaulish vindos, Breton gwenn "white;" Goth., O.Swed., O.E. witan "to know;" Goth. weitan "to see;" Eng. wise, Ger. wissen "to know;" Lith. vysti "to see;" Bulg. vidya "I see;" Pol. widzieć "to see," wiedzieć "to know;" Rus. videt' "to see," vest' "news," O.Russ. vedat' "to know"). The meaning "sense of sight" is first recorded c.1491. Meaning "statesman-like foresight, political sagacity" is attested from 1926. The etymological connection between knowledge and vision is interesting. Wisdom and vision seem to have the same root. Also interesting how vision was first about sensing supernatural things and then later came to be about sense of sight.
