It was first used by Aristotle, whose 10 categories formed a list of all the ways in which assertions can be made of a subject. Immanuel Kant's 12 categories constitute an exhaustive list of the a priori forms through which a person knows the phenomenal world. The term has also been used in many other senses by various philosophers.category 1. Metaphysics any one of the most basic classes into which objects and concepts can be analysed 2. a. (in the philosophy of Aristotle) any one of ten most fundamental modes of being, such as quantity, quality, and substance b.

Category in linguistics, linguistic meanings that are correlated and interrelated on the basis of a common semantic feature and represent a closed system of subdivisions of this feature. Examples are the category of person in the Russian language (encompassing three meanings, based on the feature of participation in the act of speech), the category of gender in Russian adjectives, and the lexical category of color designation. Categories are distinguished according to the nature of their semantics (denotative, semantic-syntactical), the degree of their obligatory use in a given language (grammatical, nongrammati-cal), and the means of expression (morphological, lexical, syntactical). Categories that are semantically close may be obligatory in some languages and optional in others. Thus, the category of locative relationships among nouns is expressed in the Lak language by a category comprising a series of locative cases (k“atluin, “to the house”; k“atluinmai, “in the direction of the house”; k“atluikh, “above the house and past it”), whereas in Russian the corresponding meanings are expressed by separate lexical units. The grammatical (obligatory) categories in a language form rigid hierarchical systems. For example, categories expressed by the noun in Hungarian include number, possession, the person and number of the possessor, the relative, the number of the relative, and case. B. IU.
