ΚΑΙΡΟΣ
Kairos, in contrast to chronos, is not merely the succession of moments, but the qualitative, decisive moment, the opportune occasion. It is the critical juncture for action, the 'golden mean' in art and rhetoric, the divinely appointed period in Koine Greek. Its lexarithmos (401) suggests the balance and completeness that characterize the ideal moment.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, *kairos* (καιρός) primarily means “the right, proper, or opportune time, season, or occasion.” It fundamentally differs from *chronos* (χρόνος, ὁ), which refers to the quantitative, linear, and uninterrupted flow of time. *Kairos*, conversely, denotes a specific, qualitative moment, a “window” of opportunity, or a critical turning point.
The concept of *kairos* gained particular significance in ancient Greek philosophy and rhetoric. Sophists such as Gorgias and Isocrates elevated it as a central element of persuasion, emphasizing the necessity of speaking the right thing at the right moment. In medicine, particularly in Hippocratic texts, *kairos* refers to the critical phase of an illness, where the outcome is uncertain and immediate, correct intervention is required.
Aristotle, in his ethics, employs *kairos* to describe the ideal moment for the manifestation of a virtue, stressing that a virtuous act is not only morally correct but also temporally appropriate. In Hellenistic and Koine Greek, *kairos* often acquires theological dimensions, referring to “God’s time,” i.e., the moment appointed by God for the fulfillment of His plans, as it appears in the New Testament.
Etymology
From the same root derive words expressing the timeliness or untimeliness of an event, such as *eukairia* (εὐκαιρία, “good, opportune moment”) and *dyskairia* (δυσκαιρία, “bad, inopportune time”). Similarly, the adjective *kairios* (καιρίος, “opportune, critical”) and the adverb *kairiōs* (καιρίως, “opportunely, critically”) belong to the same family, underscoring the central idea of temporal precision and the significance of the moment.

- Season, period of the year — A specific season or period, often associated with weather conditions. «χειμέριος καιρός» (winter season) — Homer, *Odyssey* 5.317.

Word Family
kair- (root of the verb keirō, meaning 'to cut, divide')
The root 'kair-' derives from the verb *keirō* (κείρω), meaning 'to cut' or 'to divide.' From this initial sense of division and the determination of a point, the meaning evolved to signify 'a determined time' or 'a critical moment.' The family of words generated from this root focuses on the quality of time, the appropriateness or inappropriateness of a circumstance, and the need for precise and timely action. Each member of the family illuminates a different aspect of this fundamental temporal concept.
