What does eternality mean?
"Eternality" is an abstract noun denoting the state or quality of being eternal — that is, of existing without beginning or end, or enduring indefinitely. It is closely related to, and far less frequently used than, "eternity," which usually denotes endless time itself; by contrast, "eternality" names the property of endlessness, which makes it especially at home in philosophy and theology. Writers speak of the eternality of God, of the soul, or of abstract entities such as numbers or truths, particularly in traditions that distinguish between beings that exist within time and those that exist outside it altogether. The word is formal in register and rarely appears in everyday conversation; most speakers would reach for "eternity" or phrases like "timelessness" instead. Derived, like its relatives, from the Latin aeternus meaning "everlasting," it offers a precise term when the discussion calls for endlessness treated as an attribute rather than a span of time.
nounThe state or quality of being eternal; existence without beginning or end, or lasting indefinitely.
- The property or quality of being eternal; infinite duration without beginning or end.
- (In theology and philosophy) The attribute of existing outside of or transcending time altogether.
"The cathedral's stained glass seemed to capture something of the eternality of the divine."
"Medieval theologians debated whether God's eternality meant endless existence through time or existence beyond time entirely."
"The poem contrasts the eternality of the mountains with the fleeting span of human life."
Rarely pluralized; the plural appears only in contexts contrasting different notions or kinds of eternality.
"The lecture surveyed the various eternalities proposed across medieval metaphysics."
"Eternality" is the rarer sibling of "eternity" — philosophers and theologians reach for it when they need to talk about endlessness as a property rather than as time itself.

Etymology of eternality
"Eternality" derives from the adjective "eternal," which entered English from Old French, ultimately tracing back to the Latin aeternus, meaning "everlasting" or "of endless duration." Aeternus itself stems from aevum, the Latin word for age or lifetime, rooted in the Proto-Indo-European notion of vital force or long life. The noun "eternality" was formed with the abstract-noun suffix -ity, on the pattern of words like "reality" and "permanence," and has been used since roughly the early modern period alongside its older sibling "eternity." Its cognates include the French éternité and the Italian eternità.
How eternality is actually used
"Eternality" is markedly less common than "eternity" and carries a formal, often philosophical or theological register. It is typically used when discussing a property or attribute (e.g., the eternality of matter in certain metaphysical systems) rather than referring to endless time itself.
Easily confused with eternality
"Eternity" refers to infinite time or endless existence itself, while "eternality" names the abstract quality or property of being eternal.
