Etymology of breastfed
The word is a straightforward modern English compound formed from 'breast', which descends from Old English 'brēost' and shares distant Germanic roots with Dutch 'borst' and German 'Brust', and 'fed', the past form of 'feed', which comes from Old English 'fēdan'. Compounds pairing 'breast' with another word have existed in English since the medieval period, but the verb 'breastfeed' itself is comparatively recent, gaining currency in the twentieth century as infant-feeding practices became a subject of medical discussion. Cognates of 'breast' across the Germanic languages reflect a common Proto-Germanic root referring to the chest or bosom.
