Etymology

The term "and/or" is a legal and logical construct combining "and" (Old English and, meaning addition or connection) and "or" (Old English oþþe, meaning choice or alternative). It emerged in the early 19th century to clarify inclusive or ambiguous scenarios in contracts and technical writing. The slash (/) symbolizes flexibility, allowing either or both options to apply.
