Definition of the word slate

The word "slate" has its origins in Old English as "slat", which referred to a thin, flat piece of stone, usually slate. This word is likely derived from the Old Norse "slatt", meaning "flat stone" or "plate". Slate was a valuable resource in medieval times, used for making roofing, flooring, and writing surfaces. The term "slate" became specifically associated with these flat stones, which were often used for writing on with a piece of chalk or a slate pencil. In the 16th century, the word "slate" began to be used figuratively to describe a flat, smooth surface, such as a slate for writing or a slate-colored stone. Today, the word "slate" has a broader range of meanings, including a plan or schedule, as in "a slate of candidates for office".
