Etymology
The term "random" comes from the Old French word randir, which means "to run fast". It was first used in English in the 14th century to describe a person or thing that runs very fast. Over time, the meaning of the word evolved to refer to something that is unpredictable or lacks a definite plan, purpose, or pattern.
