Consanguinity is a formal, often legal word for being related by blood — sharing a family line through parents, grandparents, and so on. A parent and child, or two sisters, have consanguinity. A husband and wife do not, unless they were already blood relatives, which the law usually forbids.

Lawyers and church records care about degrees of consanguinity: how close the blood tie is. Ordinary families just say “we’re related” or “she’s my cousin.” Though actually, people sometimes use “family” for everyone at the table, including in-laws; consanguinity is stricter and only counts blood.
