* Laundry: This word has been around for centuries, originating from the Old French word "lavanderie," meaning "washing place."
* Street: This word is of Old English origin and refers to a public road.
The combination of these two words emerged in the mid-20th century when self-service laundries began to pop up along streets in cities. These businesses, often small and simple, were conveniently located for people to drop off their laundry and do it themselves.
Therefore, "laundrette" describes a laundry facility situated on or near a street, emphasizing its accessibility and convenience. It's a shorter, more informal, and more descriptive term than "self-service laundry."
