A category is a class or division of objects or concepts that have common characteristics or attributes. This term is used widely in various fields like mathematics, biology, linguistics, and philosophy, each having a specific contextual meaning. In general, it refers to the organization or grouping of things based on similarities or shared traits.
one of the highest classes to which the objects of knowledge or thought can be reduced, and by which they can be arranged in a system; an ultimate or undecomposable conception; a predicament
class; also, state, condition, or predicament; as, we are both in the same category
Etymology: [L. categoria, Gr. , fr. to accuse, affirm, predicate; down, against + to harrangue, assert, fr. assembly.]
In mathematics, a category is an algebraic structure that comprises "objects" that are linked by "arrows". A category has two basic properties: the ability to compose the arrows associatively and the existence of an identity arrow for each object. A simple example is the category of sets, whose objects are sets and whose arrows are functions. On the other hand, any monoid can be understood as a special sort of category, and so can any preorder. In general, the objects and arrows may be abstract entities of any kind, and the notion of category provides a fundamental and abstract way to describe mathematical entities and their relationships. This is the central idea of category theory, a branch of mathematics which seeks to generalize all of mathematics in terms of objects and arrows, independent of what the objects and arrows represent. Virtually every branch of modern mathematics can be described in terms of categories, and doing so often reveals deep insights and similarities between seemingly different areas of mathematics. For more extensive motivational background and historical notes, see category theory and the list of category theory topics. Two categories are the same if they have the same collection of objects, the same collection of arrows, and the same associative method of composing any pair of arrows. Two categories may also be considered "equivalent" for purposes of category theory, even if they are not precisely the same.

Cat′egories (phil.), the highest classes under which objects of philosophy can be systematically arranged, understood as an attempt at a comprehensive classification of all that exists: in Kant's system, the root-notions of the understanding, the specific forms of the a priori or formal element in rational cognition (quantity, quality, relation, modality, &c.).—v.t. Cat′egorise, to place in a category or list: to class.—n. Categor′ist, one who categorises.—Categorical imperative, in the ethics of Kant, the absolute unconditional command of the moral law, irrespective of every ulterior end or aim—universally authoritative, belonging to the fixed law of nature—'Act from a maxim at all times fit for law universal.'
