LEXARITHMOS 620

Definition

According to the Liddell-Scott-Jones Lexicon, ἔμετος is "the act of vomiting, emesis." While describing a common bodily function, the word acquires particular significance within the context of ancient Greek medicine, where vomiting was often not merely a symptom but also a therapeutic intervention. Hippocratic authors, for instance, refer to it as a means of purging the body's humors, especially in cases of excess phlegm or bile.

The concept of emesis extends beyond the simple physical act, implying the expulsion or ejection of undesirable elements. This broader meaning can be found in metaphorical uses, where something "emetic" might signify something repulsive or abhorrent, provoking a desire for rejection. The word retains its core meaning throughout Greek literature, from classical times through the Koine and Byzantine periods, primarily in medical and descriptive texts.

In modern Greek, the term "εμετός" (emetos) remains in use with the same basic meaning, while its derivatives enrich the vocabulary surrounding the act and its consequences. The root of the word underscores the antiquity of the concept and its importance in understanding human physiology and pathology since ancient times.

Etymology

ἔμετος ← ἐμέω ← *wem- (Proto-Indo-European root)
The word ἔμετος derives from the verb ἐμέω, which in turn traces back to the Proto-Indo-European root *wem-, meaning "to vomit, to retch." This root is widely attested across numerous Indo-European languages, indicating a common and ancient understanding of the act of vomiting. Examples include the Latin "vomere," Sanskrit "vamati," and English "vomit."

Cognate words include the verb ἐμέω, the adjective ἐμετικός (that which causes vomiting or is related to vomiting), the noun ἐμεσία (the act of vomiting), and ἀνέμετος (that which does not vomit or does not cause vomiting). These words consistently maintain the core meaning of expulsion from the mouth, whether as an action or a quality.

Main Meanings

  1. The act of vomiting, emesis — The primary and literal meaning, the voluntary or involuntary expulsion of stomach contents through the mouth.
  2. Therapeutic vomiting, catharsis — In ancient medicine, the induction of vomiting as a method to expel harmful humors or substances from the body, as described by Hippocrates.
  3. The contents of vomit — Metaphorically, referring to the matter itself that is expelled, not just the act.
  4. Expulsion, ejection — A broader metaphorical meaning, the rejection or driving out of undesirable elements, ideas, or situations.
  5. Disgust, abhorrence — The feeling evoked by something repulsive, to the extent of causing a desire for emesis or rejection.
  6. Emetic drug — In medical texts, it can denote a medicine or substance that induces vomiting.
