1. 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.

Explanation

If you attend school, you probably have a favorite class — a series of lectures or discussions where you can learn about a particular subject, like English, math, or economics. The characteristic of being high quality or displaying elegance is also called class. Your snobby friend might glance around your favorite diner and say, "Let's go somewhere else. This place has no class." In society, class refers to a ranking system based on socio-economics, birth, education level, or a combination of those things. Your ancestors might have been working class, until your grandfather struck it rich.
