**Sprinter** → It is formed from "sprint" (originating from the dialectal English *sprinten*, meaning to run or move quickly) and "-er" (meaning a person who). A sprinter is a person who runs quickly, especially in short distances.
Think of someone who is 'running quickly' — that's what a sprinter does, and the '-er' just means a person.
