Where does bloodstream come from?
Language of origin: Germanic
This is a transparent English compound formed from two ancient native words. 'Blood' descends from the Old English 'blod', a Germanic word for the red fluid of the body, with relatives in Dutch 'bloed' and German 'Blut'. 'Stream' comes from the Old English 'stream', meaning a flowing body of water or a current, also of Germanic origin and related to Dutch 'stroom'. The two were joined to picture blood as a moving river within the body, a metaphor that became natural once circulation was understood. The compound is recorded in English from the seventeenth century onward and grew common as medicine described how substances are carried through the veins. Because both halves are familiar everyday words, the only spelling care needed is remembering it is written as one solid word.
How the word is built
