bathtub
UK: ˈbɑːθtʌb | US: ˈbæθtʌb
n. a large container for holding water in which a person may wash or soak the body
The word "bathtub" is a straightforward compound of two Old English roots: "bath" (from bæð, meaning "immersing in water for cleansing") and "tub" (from tubbe, meaning "a broad, open vessel"). The combination emerged in the 17th century as dedicated washing vessels became common in households. The logic is literal—a "tub for baths." Both morphemes retain their original meanings, making the word highly transparent.
