Definition of the word interior

The word "interior" has its roots in Latin. It comes from the word "interior," which means "lying within" or "outer." In Latin, the prefix "inter-" means "between" or "among," and the suffix "-ior" means "of or pertaining to." So, when combined, "interior" literally means "something that is between or among the outer boundaries." The word "interior" was later adopted into Middle English from Old French, where it was spelled "interieur." In English, it initially referred to something that was internal or inner, such as the interior of a house, a cave, or the human body. Over time, the meaning of "interior" expanded to include architecture, design, and styling. Today, "interior" is commonly used to refer to the design and decor of the interior of buildings, spaces, and objects.
