Inherited from
Old English brēost via Middle English

Pronunciation

  • IPA: /brest/[1]

Etymology

It is inherited from Middle English brest, inherited from Old English brēost,[2][3][4] from Proto-Germanic *breustą,[3][4][2] which also gave Old Saxon briost, Old Norse brjóst and Dutch borst, beside a form *brusts behind German Brust and Gothic brusts.[4][2][3] Outside Germanic it is related to Old Irish brú “belly, bosom” and Russian brjukho “belly”,[3][5] perhaps literally “swelling”, from PIE Proto-Indo-European *bhreus- (“to swell, sprout”).[2][3] The Old English ēo was shortened before two consonants in late Middle English, but the spelling with ea kept the old long vowel.[3]

Earliest recorded meaning

The chest or a woman's breast: about 725 in Barnhart, in a version of Genesis; about 1000 in the OED.[3][6]

Semantic evolution

Old English already used the breast for the seat of the emotions and of secrets,[2][6] as in to make a clean breast of, to confess.[1] The corresponding part of animals is from before 1400, and a joint of meat such as chicken breast from 1530.[6] The breast as a figurative source of nourishment is from 1611.[6] Breastplate is from the late 14th century, and breast-pump from 1821.[2] The verb, to push the breast against waves or wind, is from 1599, and to meet boldly from 1850;[6][2] runners breast the tape at the finish.[7]
