What does integument mean?
An integument is a covering, especially the natural outer covering of an organism. The word is most commonly used for skin and closely associated structures, but it can also describe protective layers around organs, seeds, or other biological parts. In zoology, an animal's integument may include scales, feathers, fur, or shells in addition to skin; in botany, it can refer to layers surrounding a seed or other plant structure. Compared with skin, integument is a more formal and technical term. In everyday use, it can more generally suggest an outer layer that protects something beneath it. The word is especially useful in biology and related fields because it identifies the covering function of a structure without requiring a more specific anatomical term.
nounAn integument is a natural outer covering, especially the skin and its associated structures. In biology, the term refers more broadly to any protective layer surrounding a body, organ, or other biological structure.

Your skin is your body's best-known integument, but turtles, pangolins, and tree trunks all have their own protective outer layers.

Where does integument come from?
The word entered English in the late Middle English period from the Latin integumentum, meaning “a covering” or “something that covers.” Latin integumentum was derived from integere, “to cover,” which is related to the root shared by words such as tegere, “to cover,” and tegumentum, an older or alternative form. In later English usage, the word developed its specialized biological meaning for the outer covering of an organism.
