ΕΛΛΕΙΨΙΣ

LEXARITHMOS 990

The term ἔλλειψις, deeply embedded in ancient Greek thought, denotes absence, omission, or deficiency. From astronomy, where it refers to the "eclipse" of celestial bodies, to geometry, defining the "ellipse" as a conic section, and rhetoric, as the "omission" of words, its meaning revolves around the concept of "lacking" or "falling short." Its lexarithmos (990) suggests a fullness (9) approaching perfection, yet also an absence (0) creating a void, reflecting the very notion of incomplete completeness.

Definition

According to the Liddell-Scott-Jones Lexicon, ἔλλειψις originally means "omission, abandonment, deprivation, deficiency." The word derives from the verb ἐλλείπω, meaning "to leave out, omit, lack, fall short." Its meaning expanded into various fields of ancient Greek science and art.

In geometry, ἔλλειψις constitutes one of the three conic sections, as defined by Apollonius of Perga in his "Conics." It was so named because the application of the area (parabola) "falls short" (ἐλλείπει) of the square formed on the ordinate, i.e., the area is less than expected. This concept of "lacking" or "falling short" is central to its definition.

In astronomy, ἔλλειψις refers to the "eclipse" of celestial bodies, such as a solar or lunar eclipse, where one body covers or deprives another of light. In grammar and rhetoric, "ellipsis" is the omission of a word or phrase that is understood from the context, a figure of speech used for brevity or emphasis. Its widespread use underscores the central importance of the concept of absence or deficiency in Greek thought.

Etymology

ἔλλειψις ← ἐλλείπω ← ἐν + λείπω. The root is the Ancient Greek verb λείπω, meaning "to leave, abandon, lack, be deficient."
The etymology of ἔλλειψις derives from the verb ἐλλείπω, which is formed from the preposition ἐν- (here denoting "in," "within," or intensity, but also "in relation to") and the verb λείπω. The root λειπ- is an Ancient Greek root belonging to the oldest stratum of the language, expressing the concept of removal, abandonment, or deficiency. From this fundamental meaning, all derivative senses of lack, omission, and deprivation developed.

From the root λειπ- stems a rich family of words expressing various nuances of absence, deprivation, or remainder. The verb λείπω forms the core, while the addition of prepositions such as ἐν-, παρά-, ἀπό-, ἐκ- and suffixes like -σις, -μα, -ής, creates nouns, adjectives, and other verbs that specialize the original meaning. Thus, this family covers a wide range of concepts, from simple omission to complete eclipse and residual elements.

Main Meanings

  1. Deficiency, deprivation, lack — The general meaning of the absence or insufficiency of something. E.g., "ἔλλειψις τροφῆς" (lack of food).
  2. Omission, verbal ellipsis (rhetoric/grammar) — The intentional or unintentional omission of words or phrases in a sentence, understood from the context. A figure of speech.
  3. Eclipse (astronomy) — The phenomenon where a celestial body covers or deprives another of light, such as a solar or lunar eclipse.
  4. Ellipse (geometry) — One of the three conic sections, defined as the curve resulting when a cone is intersected by a plane at a specific angle. Named for the "deficiency" in the application of areas.
  5. Failure, falling short — The inability to achieve a goal or the shortfall in relation to a standard or expectation.
  6. Departure, abandonment — Less commonly, the act of leaving something or withdrawing from a place.

Word Family

λειπ- (root of the verb λείπω, meaning "to leave, to lack")

The root λειπ- is fundamental in the Ancient Greek language, expressing the action of "leaving," "abandoning," or "lacking." From this basic concept, a wide range of meanings developed concerning absence, deficiency, omission, but also the remainder or residue. The addition of prepositions (such as ἐν-, παρά-, ἀπό-, ἐκ-) and suffixes (-σις, -μα, -ής) allowed for the creation of words that specialize the original meaning across various fields, from grammar and rhetoric to geometry and astronomy, making this family central to expressing the concept of imperfection or incompleteness.

«ἐὰν μὲν οὖν ἐλλείπῃ τὸ τετράγωνον τοῦ παρακειμένου χωρίου, ἔλλειψις καλεῖται»
If then the square falls short of the adjacent area, it is called an ellipse.
Apollonius of Perga, Conics, Book I, Definition 11
«ἔστι δὲ ἔλλειψις λόγου ἢ λέξεως, ὅταν ἐκ τῶν συμφραζομένων νοῆται»
Ellipsis is the omission of a phrase or word, when it is understood from the context.
Dionysius Thrax, Art of Grammar, Chapter 17
«τὸ γὰρ ἀγαθὸν καὶ τὸ τέλος, ὅπερ ἐστὶν ἑκάστου, οὐκ ἔχει ἔλλειψιν»
For the good and the end, which is the end of each thing, has no deficiency.
Aristotle, Nicomachean Ethics, Book I, 1094a
