ΠΛΗΘΟΣ

LEXARITHMOS 397

The Greek word plēthos (πλῆθος) encapsulates far more than mere quantity; it delves into the very essence of collective existence. From its basic meaning of "fullness" or "multitude" to its profound political implications as "the common people" or "the mob," plēthos illuminates the dynamic interplay of aggregation and collective action. Its lexarithmos (397) resonates with concepts of completeness and transformation.

Definition

According to the Liddell-Scott-Jones Greek-English Lexicon, πλῆθος (τό) primarily signifies "fullness, completion," as of a vessel or a space. This foundational sense rapidly expanded to describe a large quantity or number of things or people, thus "multitude, great number, mass." The word is ubiquitous in ancient Greek literature, from Homeric epics to philosophical treatises and historical narratives, underscoring its central importance in describing the world and society.

In the political and social sphere, πλῆθος acquires particular weight. It can refer to "the people" or "the many" (οἱ πολλοί), often in the sense of the common populace, the masses, or even the mob, especially when contrasted with "the few" (οἱ ὀλίγοι) or "the nobles." This distinction is fundamental to understanding ancient Greek political systems such as democracy, oligarchy, and aristocracy, where power was exercised either by the πλῆθος or by a smaller, select group.

Beyond its quantitative dimension, πλῆθος can also denote "abundance" or "plenitude" in a more abstract sense, such as the fullness of time or the abundance of goods. In philosophy, particularly in Plato and Aristotle, the concept of πλῆθος is examined in relation to "the one" and "the many," exploring the nature of unity and multiplicity and how they coexist in reality. The word, therefore, functions as an indicator not only of numerical aggregation but also of the substance of collective existence and completeness.

Etymology

πλῆθος ← likely from PIE root *pleh₁- "to fill"
The etymology of πλῆθος is closely linked to the Proto-Indo-European root *pleh₁-, meaning "to fill" or "to be full." This root has given rise to numerous words across various Indo-European languages related to fullness, abundance, and large numbers. The original meaning of πλῆθος as "fullness" or "filling" is evident and preserved in many of the word's usages.

Cognate words include the verb πίμπλημι (to fill), the adjective πλήρης (full), the noun πλησμονή (fullness, satiety), and the adverb πλήν (except, save). In Latin, this root corresponds to *plenus (full) and *pleo (to fill), yielding words such as *plenitude* and *plenty*. In English, cognates include *full* and *fill*.
