ΠΕΡΙΟΔΟΣ
The word periodos, encapsulating the concept of cycle and completion, from the revolution of celestial bodies in ancient astronomy to the harmonious structure of a rhetorical sentence. Its lexarithmos (539) suggests cyclical movement and return, elements central to its scientific and philosophical usage.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, periodos (περίοδος, ἡ) primarily means "a going round, circuit, circumference." The word is a compound, derived from the preposition "peri" (around, about) and the noun "hodos" (way, path). This composition suggests a path that returns to its starting point or that is executed around something.
The meaning of the word quickly expanded from literal movement to abstract concepts. In astronomy and physics, it refers to the regular recurrence of phenomena, such as the period of planets or seasons. In philosophy, it can denote a cycle of thought or a complete course of arguments.
Particularly significant is its use in rhetoric, where "periodos" describes a complete, harmoniously structured sentence or clause, which begins and ends in a way that creates a sense of fullness and continuity. This rhetorical period is composed of smaller units, the cola and commata, but the period itself is the overarching unit.
In everyday language, periodos refers to a duration of time, a cycle of events, or even the course of a disease. The breadth of its meanings reflects the central idea of circular motion, repetition, and completion inherent in its composition.
Etymology

Examples include the verb "hodeuō" (to go, travel), the noun "hoditēs" (traveler), as well as numerous compounds with various prepositions that specify the direction or manner of the journey, such as "exodos" (exit), "eisodos" (entrance), "proodos" (progress), "kathodos" (descent), "methodos" (method), and "synodos" (assembly, meeting).
