equipment

Equipment entered English around the 1720s from French équipement, the noun form of équiper (to fit out or supply). The French verb came from Old Norse skipa, meaning to arrange or man a ship, which derived from skip, the Old Norse word for ship itself. The connection to ships is not metaphorical: the earliest sense of équiper in medieval French referred specifically to outfitting a vessel with crew, provisions, and weapons. To equip a ship was to make it ready to sail; to equip anything was, by extension, to make it ready for its purpose.

The Old Norse skip shares its Proto-Germanic root skipą with the English word ship and the German Schiff. Norse sailors settled along trade routes into Normandy beginning in the 9th century, and their maritime vocabulary settled with them. The Normans absorbed skipa into their French dialect as équiper, and when Norman French became the administrative language of England after 1066, many of these nautical terms moved inland and lost their connection to water entirely. A word born on the deck of a longship eventually described the contents of a soldier's pack.

In 17th-century French military usage, équipement referred to the full outfitting of a soldier: his weapons, his uniform, his provisions. Early 18th-century English texts use equipment almost exclusively in military and expedition contexts. By the mid-19th century the word had widened to cover the tools of any trade, a photographer's equipment, a surgeon's equipment, a farmer's equipment. The ship had become a metaphor for any organized endeavor, and what you took aboard it was your equipment.

What the word preserves is the idea of preparation for a specific purpose. Equipment is not just objects; it is objects made purposeful by the task they serve. A hammer lying in a field is a hammer. That same hammer on a carpenter's belt is equipment. The word has traveled from the deck of a Viking longship to the operating room without losing that original sense of made ready to go.
