consanguinity

/ˌkɒnsæŋˈgwɪnɪti/
IPA guide

Other forms: consanguinities

The noun consanguinity means "relation by blood," so if you want to dazzle your brother, point out that consanguinity isn't the only reason you hang out with him — he's also a great guy!

Consanguinity comes from the Latin com- "together" and sanguineus "of blood," which itself can be traced back even farther, to the early 14th century when the Old French word sanguin (fem. sanguine) meant "a type of red cloth." So blood gets its name from the vivid red color it matches, and consanguinity describes the people who, as family members, share the same blood.
