Eskhatos

Eskhatos, also transliterated eschatos, is a Greek word meaning "last" or "furthest." It serves as a linguistic root in several terms used across theology, philosophy, and literature. The most common derivatives are eschatology (the study of the end times), the eschaton (the end of the world or the ultimate culmination of history), and eschatistic forms in various texts. In classical Greek, eshatos described the final part of a sequence or the farthest point in distance or extent; in later religious usage, it came to signify events surrounding death, judgment, and the ultimate destiny of humanity.

In religious contexts, eschatology is a defined field that examines beliefs about the end of the world, resurrection, judgment, heaven and hell, and the ultimate fulfillment of divine promises. The term also appears in secular philosophy and literary criticism to discuss ideas about the end of history, final causes, or apocalyptic and post-apocalyptic narratives. The transliteration eskhatos emphasizes the Greek pronunciation more closely by representing the aspirated sound, though eschatos is more common in many English-language texts.

Eschkatos is thus the base concept behind a family of terms concerned with endings, boundaries, and the ultimate limits of processes or histories. Related terms include eschaton and eschatology, while discussions of apocalypse or end-times concepts often invoke eschatic or eschatological framings.
