"Darn" is a term used to describe the act of repairing a hole or a worn area in fabric, typically in socks or other clothing. This process involves weaving thread through the damaged area to restore its integrity and extend the life of the garment. Darning is often done by hand and can be a practical skill for maintaining clothing. The word "darn" can also be used as a mild expletive, expressing frustration or annoyance. It is considered a softer alternative to stronger curse words. This usage is common in everyday language, often employed to convey emotions without being overly offensive.
