Related by blood; descended from the same ancestor; sharing a common bloodline or family descent.
From Latin 'consanguineus,' composed of 'con-' (with, together) and 'sanguineus' (bloody, of blood, from 'sanguis' meaning blood); literally 'of the same blood.'
The word 'consanguine' is built on the Latin idea of blood as the defining factor of family—which is why so many legal and medical terms about family relationships use 'sanguine' as their root, connecting kinship to the literal substance of blood!
