Definition of keep off

The phrase "keep off" is a common instruction found on signs, usually placed in areas that people are advised not to enter or walk on. The origin of this expression can be traced back to the Old English language. The Old English word "ceapen," which means "constrain, hinder," is the root of the modern English word "keep." During the Middle English period, the word "keepe" evolved to mean "to hold, restrain, or maintain." When combined with the Old English word "of," which means "from or away," the word "keep off" emerged as a directive to warn people to stay away from a specific area or object. The phrase "keep off" first appeared in written form during the early 16th century, and its usage has since remained consistent. Today, the words "keep off" are widely used in various contexts, including road signs, building safety signs, and sporting equipment for children. In summary, the expression "keep off" is a modern adaptation of Old English and Middle English words that have evolved over time to serve as a cautionary instruction.
