serger

This term refers to a specific piece of equipment used primarily in garment construction to create a professional, clean finish on fabric edges. It is distinct from a standard lockstitch sewing machine because it performs three actions simultaneously: trimming the excess fabric, overcasting the edge, and sewing the seam.

In professional tailoring and home sewing contexts, the term is often used interchangeably with "overlocker," though "serger" is more prevalent in North American English. Users typically employ this machine to prevent fraying on woven fabrics, making it an essential tool for high-quality apparel production.
