I'm looking for a word for "All Being" to describe deity existing, always existing, and existing for eternity.

Other words often used to describe deity include:

  1. omnipotent—all powerful
  2. omnipresent—present everywhere at the same time
  3. omniscient—all knowing

None of these words describe a being/deity that has always existed and will always exist. A being that exists because he/she exists; i.e., needs nothing/nobody else to define his/her existence.

Does such a word exist?

    "Eternal" works for me

    @Jeremy: I have a few questions that might help us give a better answer: Where have you looked already? What kinds of words did you find? What do you find unsatisfying about them? Edit your question to include that information, and you'll get much better answers. Commented Jul 9, 2014 at 16:34

    Thanks @MattGutting I edited my question. Hopefully it's easier to understand what I'm looking for.

  • The most logical and parallel word would be omniessent (‘all-being’, i.e., being all things or always being), which I would say is immediately understandable to anyone with a good grasp of the English language and certainly to anyone with more than a smattering of Latin. Unfortunately, it seems to be so rare that dictionaries have not included it, so you would probably be seen as having made it up yourself if you used it. (Which is not necessarily a problem—depends entirely on context.) Commented Jul 9, 2014 at 17:44

    @JanusBahsJacquet If you think omniessent is rare, just try looking up aeviternal. :)

This may verge into theology here; but if you want to talk about the relationship of a deity to time, one common word is eternal:

: having no beginning and no end in time : lasting forever
: existing at all times : always true or valid


Saint Thomas Aquinas, in his Summa Theologica, defines eternity (following the Christian philosopher Boethius) as

the simultaneously-whole and perfect possession of interminable life

and argues that this characterizes God.

If this is what you're looking for, use the word eternal.

  • Yes, I think this captures what I'm trying to describe. I suppose there isn't one word that means what Thomas Aquinas said.

    He was talking about the single word "eternal"; that's the word to use. Commented Jul 9, 2014 at 17:49
  • Yeah, eternal was the word I was thinking of. Embarrassed this don't come to mind earlier.

The Everlasting:

   Sempiternal, Æviternal, Omniëssent, & Omnitemporal

It is not clear why eternal or everlasting wouldn’t be good enough as is, but if you want a higher-falutin’ term, the most obvious answer is sempiternal, which the OED defines as:

Enduring constantly and continually; everlasting, eternal.

That takes the Latin semper meaning “ever” or “always” and combines it with ‑ternal to produce a fancy word meaning “everlasting”.¹

The OED also attests the adjective ever-being with the sense “that which always is”, although the resulting noun everbeingness the OED considers obsolete.

A rather less common word with the same meaning as sempiternal is aeviternal (also spelt æviternal), which the OED defines as:

Everlasting, endless, eternal.

This time it comes from aevum meaning “an age”, which is related to aeon (sometimes spelt æon or eon) and thence to Greek αἰών.

This is related to but different from longeval (also spelt longaeval or longæval), which just means long-lasting or long-lived, not ever-lasting or ever-living. But you can see the same aevum root at work, this time at the end of the word instead of at its beginning.

The word omniessent (also spelt omni-essent or omniëssent) that was kindly suggested by Janus in a potentially ephemeral² comment is simply the adjective corresponding to the noun omni-essence, which the OED defines as:

universal essence or being

To me omniessent more suggests ubiquity of being than it does omnitemporaneity of the same.

Speaking of omnitemporaneousness, that brings me to my final entry, omnitemporal, defined by the OED as:

relating to all times; including in its meaning all the various tenses

Summary: Native or Fancy?

These are all long and highly fancy — perhaps even fanciful — words built of Latinate roots from antiquity instead of being built of native roots the way everlasting and everbeing are.

As such, they might have a place in a lofty register such as that of Aquinas, but for more casual ones, simpler words are likely better.


  1. This is like how sempervirent is a fancy word that means “evergreen”, visible in the taxon for the coast redwood, Sequoia sempervirens.

    One should take some care not to confuse sempervirent with sempervivent, where the latter means “everliving” or “lives-forever”, a term once applied to the succulent we call hen-and-chicks or houseleek and which survives as the genus Sempervivum.

  2. Where ephemeral and eternal are antonyms.

    I've seen aeviternal, or at any rate the noun form, aeviternity, used with a slightly different meaning in technical discussions: "Aeviternity differs from time, and from eternity, as the mean between them both." But I myself don't understand what Thomas is trying to get at in his discussion :-/ Commented Jul 9, 2014 at 18:27

    @MattGutting I have no earthly idea how eternity, sempiternity, and aeviternity may differ from each other; they’re each just as forevery as the next so far as I am concerned.

RHK Webster's has:

Immanent: 2. (of the Deity) indwelling the universe, time, etc.

  • Down that road lies the Increate.

I have often heard unbegotten used in this context (could not link to Oxford as that word is behind a pay-wall on their site.)

It literally means that one was not born or created, thus implying they have always existed. I see the word often used in the British Anglican church to describe God in particular but is equally applicable in any religion.

This word also very well emphasizes the not needing anyone else to exist part by explicitly meaning they had no creator by definition. It also has religious connotations, perhaps making it more appropriate here also.

To provide some examples (borrowed from the Oxford English Dictionary):

We know there is one God, alone unbegotten, alone eternal, alone without beginning, alone true, alone immortal.


The personae are distinguished by their difference in origin: the Father unbegotten, the Son begotten, the Spirit proceeding.


yes, and you already said it - omnipresent.

    Hmmm, I would say that that means "existing everywhere", in space but not necessarily in time.

  • One may need the two word phrase "eternally omnipresent" then, @Rupe.

    Commented Jul 9, 2014 at 16:38
  • Sure, @TecBrat, if the spatial thing is important to the OP. It's not clear to me, from the question, that it is. The fact that they've used "omnipresent" as an example of a word of the type that they're looking for makes me suspect that it's just "eternal" that they need, but it's not clear so you could well be right.

  • @Rupe why didn't you make "eternal" an answer? Because it seems like the answer to me. Commented Jul 9, 2014 at 17:24
  • This is really more of a comment than it is an answer.

Definition 3 of transcendent at Dictionary.com is

transcending the universe, time, etc.  Compare immanent (def 3).
