Etymology: The word's core is the Latin "sanguis," meaning blood, which also gave English "sanguine" and "sanguinary." Latin built "consanguineus" by joining the prefix "con-" ("together") to "sanguis," so the literal sense is "of the same blood." That Latin adjective was then taken into French as "consanguin," and English borrowed it from there, so the English word arrived by a French route rather than straight from Latin. Its closest relative in English is "consanguineous," which came from the same Latin source by a separate path. The two are doublets: English ended up with both forms, and they share a meaning. "Consanguine" is the shorter, less common of the pair, and it keeps the French-influenced shape that "consanguineous" lost.
