class (klās)
n.
A taxonomic category ranking below a phylum or division and above an order.
| class (klās) Pronunciation Key
A taxonomic category of organisms ranking above an order and below a phylum or division. In modern taxonomic schemes, the names of classes end in -phyceae for the various groups of algae, -mycetes for fungi, and -opsida for plants (as in Liliopsida, the class of plants also termed monocotyledons). The names of classes belonging to phyla of the animal kingdom, however, are formed in various ways, as Osteichthyes the bony fishes, Aves, the birds, and Mammalia, the mammals, all of which are classes belonging to the subphylum Vertebrata (the vertebrates) in the phylum Chordata. See Table at taxonomy. |
A group of people sharing the same social, economic, or occupational status. The term class usually implies a social and economic hierarchy, in which those of higher class standing have greater status, privilege, prestige, and authority. Western societies have traditionally been divided into three classes: the upper or leisure class, the middle class (bourgeoisie), and the lower or working class. For Marxists, the significant classes are the bourgeoisie and the proletariat.
In biology, the classification beneath a phylum and above an order. (See Linnean classification.)
Note: Mammals, reptiles, and insects are classes.
