Etymology

Origin of consanguineous

First recorded in 1595–1605; from Latin consanguineus “related by blood, kindred; blood relation, kinsman,” equivalent to con- + sanguin- (stem of sanguis) “blood” + -eus adjective suffix. Consanguineous first occurs in Shakespeare's Twelfth Night (1602), and Shakespeare may have introduced the word into English. See con-, -eous
