Oxford Dictionaries defines "laundry" as soiled clothes and linens that need to be washed or that have been newly washed. Alternatively, "to launder" means to wash or iron clothes and linens. A "laundromat" is an establishment with coin-operated machines available for public use.
Oxford Dictionaries explains that the word "laundry" originated in the early 16th century. It came from the Middle English word "lavendry," which was derived from the Old French words "lavanderie" and "lavandier." A "lavandier" is a person who washes linen. The Old French words were previously derived from the Latin words "levanda," meaning things to be washed, and "lavare," meaning to wash.
