evident: [14] Something that is evident is literally something that can be ‘seen’. The word comes via Old French from Latin ēvidēns ‘clear, obvious’, a compound formed from the intensive prefix ex- and the present participle of videre ‘see’ (source of English vision). The Latin derivative ēvidentia (from which English gets evidence [13]) meant originally ‘distinction’ and later ‘proof’, basis of the main current sense of evidence, ‘testimony which establishes the facts’. => view, vision
late 14c., from Old French evident and directly from Latin evidentem (nominative evidens) "perceptible, clear, obvious, apparent" from ex- "fully, out of" (see ex-) + videntem (nominative videns), present participle of videre "to see" (see vision).
