ETYM Cf. French classification.
In biology, the arrangement of organisms into a hierarchy of groups on the basis of their similarities in biochemical, anatomical, or physiological characters. The basic grouping is a species, several of which may constitute a genus, which in turn are grouped into families, and so on up through orders, classes, phyla (in plants, sometimes called divisions), to kingdoms.
1. A group of people or things arranged by class or category; SYN. categorization.
2. Restriction imposed by the government on documents or weapons that are available only to certain authorized people.
3. The basic cognitive process of arranging into classes or categories; SYN. categorization, sorting.
Zu den formalen Aufgaben der S. gehört auch die richtige Benennung der systemat. Kategorien. Sie werden mit lat. Namen bezeichnet, die Arten nach der von C. von Linné 1735 eingeführten sog. binären Nomenklatur in der Weise, daß dem Gattungsnamen der Artname angefügt wird; z. B. heißt innerhalb der Gatt. Apis (Biene) die Honigbiene Apis melifica (die honigmachende).
