Etymology

The word "nightgown" is a straightforward compound of "night" (Old English niht, meaning the dark period of the day) and "gown" (Old French goune, meaning a loose outer garment). Historically, "gown" referred to any long, flowing robe, and by the 14th century, it became associated with sleepwear. The combination reflects its purpose: a garment specifically designed for nighttime wear.
