Pronunciation

  • /ˈskuːbə/[1]

Etymology

It is an acronym formed from the first letters of self-contained underwater breathing apparatus.[2][3][4][5][6][7] Barnhart and Etymonline identify it as a word of American English.[8][4] It was at first written in capitals, SCUBA, and the lower-case spelling is recorded from 1957.[8][6]

Earliest recorded meaning

Apparatus that lets a swimmer breathe under water: 1952, in the title of a paper by Hahn and Lambertsen.[2][5][9] Dictionary.com dates the word to 1950–55, and the Oxford Dictionary of English to the 1950s.[10][11]

Semantic evolution

The American Heritage Dictionary notes that such an apparatus was first tested successfully in 1943, and that the short word was far easier to say than the full phrase; because its vowels fall where they can be pronounced as in an ordinary English word, it soon stopped being felt as a string of initials.[12] Hendrickson describes scuba diving as popular since the Second World War.[13] The compound scuba-diving is recorded by 1956,[4] and scuba is occasionally used for scuba-diving itself.[2][6] New verbs followed: scuba-dive from 1964,[5][8] and scuba itself, which Barnhart dates to 1969, the American Heritage Dictionary to 1973 and the OED to 1977.[5][12][2]
