Definition

According to the Liddell-Scott-Jones Lexicon, ῥοῦς (from ῥέω) signifies "a flow, stream, current, movement." It is a noun that captures the essence of continuous motion, fluidity, and change, whether referring to natural phenomena or abstract concepts. Its primary usage pertains to the movement of water, such as the current of a river or the sea, but it quickly extends to encompass any form of outflow or motion.

The word ῥοῦς is not limited to describing the movement of water. It is widely employed in medicine to denote the efflux of bodily fluids, such as blood or other secretions, thereby highlighting the transience and fragility of human existence. In philosophy, particularly with Heraclitus, ῥοῦς becomes a symbol of eternal flux, the perpetual flow of all things, where "all things flow" (πάντα ῥεῖ).

Beyond its natural and biological dimensions, ῥοῦς also acquires metaphorical meanings. It refers to the flow of speech, the eloquence and continuity of discourse, as well as the flow of time or events, implying incessant progression and the alteration of circumstances. This word, therefore, serves as a key to understanding the dynamic perception of the world in ancient Greek thought.

Etymology

ῥοῦς ← ῥέω (root ῥεF- / ῥυ-)
The word ῥοῦς derives directly from the Ancient Greek verb ῥέω, meaning "to flow, to stream." The root ῥεF- (with digamma) or ῥυ- belongs to the oldest stratum of the Greek language and expresses the concept of movement and fluidity. From this root, a rich family of words developed, describing various forms of flow and motion, both literal and metaphorical.

From the root ῥεF- / ῥυ-, numerous nouns and verbs are derived with diverse meanings. The verb ῥέω is the foundation, while nouns such as ῥοή, ῥεῦμα, ῥύσις, and ῥοῦς itself, describe the act or result of flowing. Through the use of prefixes, such as ἀπο-, δια-, ἐπι-, συν-, compound words are formed that denote specific directions or types of flow, such as ἀπόρροια (efflux), διάρροια (flow through), ἐπιρροή (inflow, influence), and συρροή (confluence).

Main Meanings

  1. Flow of water, river or sea current — The primary and most literal meaning, referring to the movement of the aquatic element.
  2. Flow of blood, bodily fluid discharge — A medical term for the efflux of blood or other fluids from the body, often in a pathological state.
  3. Flow of speech, eloquence — Metaphorical use for the continuous and effortless delivery of speech, rhetorical skill.
  4. Flow of time, succession of events — The incessant movement of time or the continuous progression of occurrences.
  5. Outflow, capital outflow — A rarer, economic usage for the movement of money or resources.
  6. Movement, impulse, direction — A more general meaning for any kind of motion or orientation.
  7. Flux, state of fluidity — A philosophical concept denoting the constant change and transformation of all things.
