Origin of idea
historical usage of idea
The Greek noun idéa comes from the very common, very complicated Proto-Indo-European root weid-, woid-, wid- “to see.” In Greek the variant woid- forms the verb oîda ( woîda in some dialects), meaning “I know.” (In form, oîda is a perfect tense used to show a present state: “I have seen, I know.”)
Woidos, a noun derived from woid-, becomes veda- “knowledge” in Sanskrit ( Rig-Veda means “knowledge of the hymns, sacred stanzas”). The variant wid- forms the Greek noun idéa, and the infinitive ideîn (also wideîn ), the Latin infinitive vidēre, and the Slavic (Czech) vidět, all meaning “to see.”
Weid-, woid-, wid- become wīt-, wait-, wit- in Germanic. The suffixed form wīt-to- forms the adjective wīsaz, Old English wīs (English wise ), and Old English wīsdōm “learning” (English wisdom ).
