Century Dictionary and Cyclopedia
    • n classification The act of forming a class or of dividing into classes; the act of grouping together those beings or things which have certain characters in common; distribution into sets, sorts, or ranks; taxonomy. In natural history classification has been made on two principles, distinguished as the natural and the artificial: the former aiming to arrange all known plants or animals according to their resemblances, and degrees of resemblance, in the whole plan of their structure; the latter arranging them by some one or more points of resemblance or difference, as may be most convenient and easy, and without regard to other considerations. The widest divisions in zoology are called subkingdoms; subkingdoms are divided into phyla or classes, classes into orders, orders into families, families into genera, genera into species, and species into varieties. There are also intermediate divisions, as subclass, superorder, suborder, subfamily, etc. In botany the same divisions are used as in zoology, except that orders and families are identical, and the term phylum is not used. See animal kingdom, under animal, and class, 5.
    • n classification In shipbuilding, the assignment to and arrangement of merchant vessels in classes by registration societies. See class, n., 8.
