How do you spell Hannukah?
c.1600, from Latin hybrida, variant of ibrida "mongrel," specifically "offspring of a tame sow and a wild boar," of unknown origin but probably from Greek and somehow related to hubris. A rare word before c.1850. The adjective is attested from 1716.
An organism that is the offspring of two parents that differ in one or more inheritable characteristics, especially the offspring of two different varieties of the same species or the offspring of two parents belonging to different species. In agriculture and animal husbandry, hybrids of different varieties and species are bred in order to combine the favorable characteristics of the parents. Hybrids often display hybrid vigor. The mule, which is the offspring of a male donkey and a female horse, is an example of a hybrid. It is strong for its size and has better endurance and a longer useful lifespan than its parents. However, mules are sterile, as are many animals that are hybrids between two species.
