Capricorn

zodiac sign represented as a goat, or half-goat half-fish, late Old English, from Latin Capricornus, literally "horned like a goat," from caper (genitive capri) "goat" (see cab) + cornu "horn," from PIE root *ker- (1) "horn; head." A loan-translation of Greek Aigokheros, the name of the constellation. Extended 1894 to persons born under the sign.
