blood
/blʌd/·블러드·noun
the red fluid in the body; lineage
Old EnglishCEFR A2
Root
Proto-Germanic '*blōdą' (blood)
Proto-Germanic *blōdą → Old English blōd → Modern blood. Outside the Germanic branch, Latin used sanguis instead — no shared root.
In a word
This word has no Latin cousin. English blood came straight from Germanic *blōdą; for the same substance, Latin used a different root, sanguis (root of English sanguine). For one and the same thing — blood — the Germanic branch and the Latin branch raised different words separately. Inside English, blood lives in daily speech and sanguine in scholarship and literature. Two etymologies cohabit on one object.
Examples
Her hands were covered in blood.
They are bound by blood.
