risk: [17] The ultimate origins of risk have never been satisfactorily explained. English acquired it via French risque from Italian risco, a derivative of the verb riscare ‘run into danger’, but there speculation takes over. One persistent theory is that its ancestral meaning is ‘sail dangerously close to rocks’, and attempts have been made to link it with Greek rhīza ‘cliff’ and Latin resegāre ‘cut off short’ (from the notion of coastal rocks being ‘cut off sharply’ or ‘sheer’). English acquired the French past participial form risqué in the 19th century.
