Drilling → It is formed from "drill" (from Middle English *drillen*, meaning to bore or pierce) and the suffix "-ing" (indicating the action or process). The word "drilling" refers to the action or process of boring a hole or creating a passage.
Think of the action of 'boring' or 'piercing' something, which is what drilling means, combined with the '-ing' that shows it's an ongoing action.
