consanguinity

The word 'consanguinity' is a direct inheritance from Late Latin 'consanguinitas,' which itself was built from classical Latin components. The prefix 'con-' (together) was combined with 'sanguis' (blood) and the abstract noun suffix '-itas' to form a term literally meaning "the condition of being of the same blood." This Latin construction was a calque of the Greek concept expressed by words like 'homaimon,' which also meant "of the same blood." The term entered English in the late Middle Ages, primarily through legal and ecclesiastical contexts where precise definitions of familial relationship were crucial for matters of inheritance, marriage prohibitions, and dynastic claims. Its modern meaning retains this core logic, defining kinship through shared biological descent rather than marital or legal ties.

Structure: con (together) + sanguin (blood) + ity (noun suffix) con: Latin origin, a prefix meaning "together, with." sanguin: Latin origin, from 'sanguis' meaning "blood." It functions as the core root indicating blood. ity: Latin origin, a noun-forming suffix indicating a state or condition.
