Pronunciation

  • /ˈswɪm.s(j)ut/[1]

Etymology

It is a compound from English swim + suit,[2][3][4] a commercial word in which swim has the notion "worn while swimming".[2]

Earliest recorded meaning

A woman's bathing costume: 1920, according to Etymonline.[2] Merriam-Webster gives 1926 as its first known use,[5][6] Dictionary.com dates it to 1925–30,[3] and the OED's first quotation is from the Times of 18 July 1934.[7]

Semantic evolution

Etymonline notes that swimming-costume in the same sense is recorded by 1844, long before swimsuit.[2] The word was first used of women's costumes,[2][7] and Collins still defines it as a woman's one-piece garment that leaves the arms and legs bare;[8] American dictionaries define it more broadly as any garment worn for swimming.[9][6][5]

  • 1920 – a woman's bathing costume.[2]
