The word "runner" originates from the Old English "rinnan" (to run), which evolved into the Middle English "rennen." The suffix "-er" is a productive agentive suffix in English, used to denote a person or thing that performs an action. The combination "run + er" logically forms "one who runs," reflecting its primary meaning. Over time, the term expanded metaphorically to include objects or mechanisms that "run" in a linear or repetitive manner (e.g., plant runners, machine runners).
