bell-bottom

The term "bell-bottom" is a transparent compound formed from two native English words, "bell" and "bottom," to create a vivid descriptive term for a style of trousers. The logic is purely visual and functional: the "bottom" (the lower leg opening) of the trousers flares out dramatically, mimicking the shape of a "bell." This style, originally developed for sailors in the 19th century to allow trousers to be easily rolled up and to facilitate removal if the wearer fell overboard, entered mainstream fashion in the 1960s. The word's formation follows a common English pattern of combining two concrete nouns to name a new object based on its most distinctive physical characteristic.

Structure: bell (shape) + bottom (lower part) - bell: From Old English belle, meaning a hollow, resonant metallic instrument. In this compound, it functions as a noun used attributively to describe a shape resembling the flared opening of a bell. - bottom: From Old English botm, meaning the lowest part or foundation. In this compound, it functions as a noun referring to the lower part of a garment, specifically the trouser leg.
