Origin & History of “breast”
Breast can be traced back via prehistoric Germanic *breustam to an Indo-European base *bhrus- or *bhreus-, whose other descendants, including Old Saxon brustian ‘bud’, middle high German briustern ‘swell’, and Irish brú ‘abdomen, womb’, suggest that the underlying reference contained in the word may be to the growth and swelling of the female breasts. By the time it reached Old English, as brēost, it had already developed a more general, non-sex-specific sense ‘chest’, but the meaning element ‘mammary gland’ has remained throughout, and indeed over the past two hundred years ‘chest’ has grown steadily more archaic.
