Speeding → It is formed from "speed" (from Old English *spēd*, meaning success or prosperity) and "-ing" (a suffix used to form present participles). The word "speeding" refers to the act of moving quickly or with high speed.
Think of 'speed' as success in moving fast, and the '-ing' shows it's happening right now — that's why speeding means moving quickly.
