The word "pointer" originates from the Middle English term "pointour" which was derived from the Old French word "pointour" or "pointeour". It refers to something or someone that points, indicating direction or highlighting specific things. This can be traced back to the Latin word "punctum", meaning "a point". The term "pointer" was eventually used to describe a dog breed trained to point out the location of game birds for hunters. Over time, it also acquired the meaning of a cursor on a computer screen or a device used for indicating or selecting something on a display.
