guide: [14] The ancestor of guide was Germanic *wit- ‘know’, source of English wise, wit, and witness. From it was derived a verb *wītan, and the Franks, a West Germanic people who conquered Gaul in the 3rd and 4th centuries AD, brought it with them. It eventually became Old French guider, and was borrowed by English. The semantic progression from ‘knowing’ to ‘showing’ is also displayed in the related German weisen ‘show, direct, indicate’.
