A scheme, plan, simple mechanical contrivance; also a pattern or design, particularly an heraldic design or emblem, often combined with a motto or legend. "Device" and its doublet "devise" come from the two Old French forms "devis" and "devise" of the Latin "divisa," things divided, from "dividere," to separate, used in the sense of to arrange, set out, apportion. "Devise," as a substantive, is now only used as a legal term for a disposition of property by will, by a modern convention restricted to a disposition of real property, the term "bequest" being used of personalty. This use is directly due to the Medieval Latin meaning of "dividere" = "testamento disponere." In its verbal form, "devise" is used not only in the legal sense, but also in the sense of to plan, arrange, scheme.
