cardigan
UK[ˈkɑːdɪɡən]US[ˈkɑːrdɪɡən]
n
A knitted sweater or jacket, typically with an open front fastened by buttons or a zipper.
Etymology
The word 'cardigan' is an eponym, derived directly from the name of a British army officer, the Earl of Cardigan. He was famously associated with the Charge of the Light Brigade during the Crimean War, and a knitted woolen waistcoat worn by him and his soldiers became popular. The garment's name was thus transferred from the person to the item of clothing. Over time, the term evolved to refer specifically to a type of open-front knitted sweater, losing its direct association with the historical figure while retaining the name.
Analysis
The word is a proper noun adopted as a common noun. It originates from the title of James Thomas Brudenell, 7th Earl of Cardigan (1797–1868).
