Definition of sectional

The word "sectional" has its roots in the 15th century, derived from the Latin words "secare," meaning "to cut," and "sectio," meaning "a cutting" or "division." In English, the word initially referred to a division or separation, often used in a mathematical or figurative sense. In the 17th century, the term began to be used in a more specific sense, referring to a division or part of a larger whole, such as a geographic region or a socio-economic group. For example, a "sectional" might refer to a distinct area of a county or a particular social class. In modern usage, the term "sectional" is often used in various contexts, including politics (e.g., "sectional interests"), sociology (e.g., "sectional identity"), or design (e.g., "sectional couch").
