Pronunciation

  • US: /ˌpɹi.məˈtʊɹ/, /ˌpɹi.məˈt͡ʃʊɹ/[1]

Etymology

It is borrowed from Latin praemātūrus (“very early, too early; ripe before the proper season”),[2][3][4][5][6][7] formed from prae- (“before”) and mātūrus (“ripe, timely”),[2][3][5][6] the source of mature.[3][6] The American Heritage Dictionary gives the Middle English adjective the sense "ripe",[8] and Barnhart thinks that some later uses may have been formed afresh in English from pre- and mature.[4] Etymonline traces the Latin adjective to Proto-Indo-European *meh-tu- (“ripeness”).[3] Johnson (1755) compared French prématuré.[9]

Earliest recorded meaning

Ripe or mature, especially before the proper season: the first record is in a Middle English translation of Palladius on husbandry (?1440), a sense the OED marks as rare and obsolete after 1656.[2][7][4]

Semantic evolution

The modern sense, "happening or done before the usual or proper time; too early, overhasty", is recorded from about 1530,[2] in the 1520s according to Etymonline and Dictionary.com,[3][10] and in the early 16th century according to the Shorter Oxford and Collins.[11][12] Johnson (1755) defined it as "ripe too soon; formed before the time; too early; too soon said, believed, or done; too hasty".[9] The medical sense, of a labour or birth before full term and of a baby born before full term, appears in 1754 in Smellie's treatise on midwifery; in recent use it means born before 37 weeks of gestation.[2] Collins defines a premature baby by a birth weight below 2500 grams.[12] The phrase premature ejaculation is attested from 1848, and its Latin counterpart, ejaculatio praecox, from 1891 in English.[3] Military slang of the late 19th century turned the adjective into a noun for a shell or other explosive that went off too soon (1882), and in 1914 into a verb for such a shell exploding early;[2][11] a premature baby has been called a premature since 1900,[2] and the American shortening preemie dates from 1927.[3][2]
