The phrase "mark off" originates from the idea of making marks or notches on a physical object, such as a stick or a tree, to represent measurements or quantities. This act of making marks was a practical way for people to keep track of things in the past, before more advanced measurement tools were available. The term "mark off" can be traced back to the Old English word "mascian," which was used to describe the act of making a mark or notch. Over time, this word evolved to the Middle English "maken minimum," meaning "to make a small difference" or "to make a distinction." In the 16th century, the phrase "mark off" began to be used more specifically to describe the process of measuring and marking out boundaries or sections, particularly in construction and surveying. The Oxford English Dictionary (OED) provides an example of this usage from 1561: "Thus first may a man view the process how elles should be marked off." Today, the term "mark off" is commonly used in a variety of contexts, from measuring and marking out materials for construction projects, to indicating distances during sports events or activities such as hiking or camping. It remains a simple and practical way for people to measure, mark, and keep track of things in their daily lives.
