consanguineous
kon-sang-GWIN-ee-uhs
/ˌconsæŋˈɡwɪniəs/
Of the same blood or origin; descended from the same ancestor.
Highly technical, used in genetics, law, and anthropology. It carries a clinical, precise tone.
The story behind the word. The Romans combined 'com-' (together) and 'sanguis' (blood) to describe those who literally shared the same blood flowing through their veins. This term has survived intact for millennia as the standard legal and medical term for blood relations.

Memory hook
Break it down: 'con' (with) + 'sang' (French/Latin for blood) + 'gwineous'. It literally means sharing blood. Con (with) + Sang (blood).
When not to use
Avoid in casual conversation; saying 'my consanguineous brother' instead of 'my brother' sounds bizarrely clinical.
Fun facts
- Consanguineous marriages were common in royal dynasties to preserve power, but often led to severe genetic disorders, famously seen in the Habsburg jaw.
