Needler → The word is formed from "needle" (from Old English "nǣdl", meaning a small, slender tool for sewing) and "-er" (meaning a person who). A needler is a person who uses a needle, typically for sewing or stitching.
Think of a 'needle' as a small tool used for sewing, and the '-er' indicates a person. So, a needler is someone who works with a needle.
