The word "pointer" originates from the verb "point," derived from Old French "point" (to prick, mark, or direct), which itself comes from Latin "punctum" (a prick or dot). The suffix "-er" is an agentive suffix in English, indicating a person or thing that performs an action. Thus, a "pointer" literally means "something that points." Over time, the term expanded to include computing contexts (referencing memory addresses) and the hunting dog breed (trained to "point" at game).
