Meaning of FAMILY in English
(v. t.) A group of organisms, either animal or vegetable, related by certain points of resemblance in structure or development, more comprehensive than a genus, because it is usually based on fewer or less pronounced points of likeness. In zoology a family is less comprehesive than an order; in botany it is often considered the same thing as an order.
