Definition of directional

The word "directional" has its roots in the 15th century. It originates from the Latin words "directionem," meaning "a leading or guidance," and "alis," meaning "pertaining to." In the early 15th century, the Latin word "directionalis" was borrowed into Middle English as "directional," initially meaning "of or pertaining to direction" or "related to guidance or leading." In the 16th century, the term took on a broader sense, referring to anything that is related to or involved in directing or guiding something. Over time, the word "directional" has evolved to encompass a range of meanings, including "relating to or indicating direction," "guiding or pointing," and "related to the control or guidance of something." Today, the word is commonly used in various contexts, including navigation, physics, and engineering.
