ΚΑΤΗΓΟΡΙΑ (kategoria_rhet) — Lexarithmos 513 · Etymology, Meanings

Definition

The word «κατηγορία» (katēgoria, ἡ) derives from the verb «κατηγορέω», meaning "to speak against someone in the assembly" or "to accuse." Its initial and predominant meaning in classical Greek was that of "accusation" or "the act of accusing" within a legal or political context. It represented the formal statement of guilt or wrongdoing brought against an individual, often before a court or assembly.

Over time, and notably with Aristotle, the word's meaning expanded to acquire a deep philosophical dimension. Aristotle employed the term «κατηγορία» to describe the ten fundamental ways in which something can be said of a subject, i.e., the modes of being or the kinds of predicates. These ten categories (such as substance, quantity, quality, relation, place, time, etc.) formed the basis for the organization of knowledge and logic in Western philosophy.

Thus, «κατηγορία» evolved from a specific legal act into a universal tool for classifying and analyzing reality and language. This dual nature, as both an act of accusation and a conceptual category, renders it one of the most significant and multifaceted words in the Greek language.

Etymology

katēgoria ← katēgoreō ← kata + agoreuō ← agora (root agor-)

The word «κατηγορία» originates from the verb «κατηγορέω», which is a compound of the preposition «κατά» ("against") and the verb «ἀγορεύω» ("to speak in the assembly, to harangue"). The verb «ἀγορεύω» in turn is derived from the noun «ἀγορά», which originally signified the place of public assembly, the public square, or the marketplace. The Ancient Greek root agor- belongs to the oldest stratum of the language and denotes the concept of gathering and public speaking.

From the same root agor- stem numerous words related to public speaking and assembly. The noun «ἀγορά» is the base, from which the verb «ἀγορεύω» ("to speak publicly") is derived. Compound verbs such as «ἀναγορεύω» ("to proclaim"), «προαγορεύω» ("to foretell"), and «ἐξαγορεύω» ("to declare fully") illustrate the variety of meanings that developed around the act of speaking. «Κατηγορία» and «κατήγορος» represent specific instances of this root, focusing on speaking "against" someone.

Class, kind, type — A more general classificatory meaning, based on the Aristotelian usage, to denote a group or division of things.
Predicate (grammar) — The part of a sentence that states something about the subject, as a grammatical concept.
