Etymology: The French "ossature" comes from "os", the Latin word for "bone", which gives the English term its core meaning of a skeletal framework. The ending "-ature" is a French suffix that turns a noun into a term for a collection or structure, so the word literally describes a bony framework assembled from parts. English borrowed the term from French, and it has kept that double life ever since: it can describe the skeleton of an animal or the internal frame of a building, bridge, or machine. Because the word stays so close to its anatomical root, its figurative use in engineering and design feels natural. A structure's ossature is the part you cannot see once the walls and surfaces are finished, which is exactly what the bone metaphor suggests.
