The word "overlays" can be traced back to the Middle English term "overleie" (late 14th century) which combines the elements "over" and "lay". "Over" comes from the Old English "ofer", meaning "above" or "on top of", while "lay" refers to the act of placing or putting down. Over time, "overleie" evolved into "overlay" in modern English, functioning both as a verb and a noun. The term refers to something that is placed on top of or covers another thing, often with the intention of adding decoration or protection.
