Aion, Aionios and the lexicons:
166. αιωνιος aionios; from 165; agelong, eternal:— eternal(66), eternity(1), forever(1).
Thomas, Robert L., Th.D., General Editor, New American Standard Hebrew-Aramaic and Greek Dictionaries,
166 aionios- αιωνιος
1) without beginning and end, what has always been and always will be
2) without beginning
3) without end, never to cease, everlasting
---Thayers
2. αιωνιος aionios [166] "describes duration, either undefined but not endless, as in <Rom. 16:25; 2 Tim. 1:9; Titus 1:2>; or undefined because endless as in <Rom. 16:26>, and the other sixty-six places in the NT.
"The predominant meaning of αιωνιος , that in which it is used everywhere in the NT, save the places noted above, may be seen in <2 Cor. 4:18>, where it is set in contrast with proskairos, lit., `for a season,' and in <Philem. 15>, where only in the NT it is used without a noun. Moreover it is used of persons and things which are in their nature endless, as, e. g., of God, <Rom. 16:26>; of His power, <1 Tim. 6:16>, and of His glory, <1 Pet. 5:10>; of the Holy Spirit, <Heb. 9:14>; of the redemption effected by Christ, <Heb. 9:12>, and of the consequent salvation of men, <5:9>, as well as of His future rule, <2 Pet. 1:11>, which is elsewhere declared to be without end, <Luke 1:33>; of the life received by those who believe in Christ, <John 3:16>, concerning whom He said, `they shall never perish,' <10:28>, and of the resurrection body, <2 Cor. 5:1>, elsewhere said to be `immortal,' <1 Cor. 15:53>, in which that life will be finally realized, <Matt. 25:46; Titus 1:2>.
αιωνιος is also used of the sin that `hath never forgiveness,' <Mark 3:29>, and of the judgment of God, from which there is no appeal, <Heb. 6:2>, and of the fire, which is one of its instruments, <Matt. 18:8; 25:41; Jude 7>, and which is elsewhere said to be `unquenchable,' <Mark 9:43>.
"The use of αιωνιος here shows that the punishment referred to in <2 Thes. 1:9>, is not temporary, but final, and, accordingly, the phraseology shows that its purpose is not remedial but retributive."

The most frequent use of αιωνιος in the NT is with zwhv ‘life,’ for example, i{na pa`" oJ pisteuvwn ejn aujtw/` e[ch/ zwh;n aijwvnion ‘so that everyone who believes in him may have eternal life’ Jn 3.15. In combination with zwhv there is evidently not only a temporal element, but also a qualitative distinction. In such contexts, αιωνιος evidently carries certain implications associated with αιωνιος in relationship to divine and supernatural attributes. If one translates ‘eternal life’ as simply ‘never dying,’ there may be serious misunderstandings, since persons may assume that ‘never dying’ refers only to physical existence rather than to ‘spiritual death.’ Accordingly, some translators have rendered ‘eternal life’ as ‘unending real life,’ so as to introduce a qualitative distinction.

αιωνιος aionios. An adjective meaning “eternal,” and found in the LXX in Pss. 24; 77:5; Gen. 21:33, aionios in the NT is used 1. of God (Rom. 16:26), 2. of divine possessions and gifts (2 Cor. 4:18; Heb. 9:14; 1 Pet. 5:10; 1 Tim. 6:16; 2 Th. 2:16, and 3. of the eternal kingdom (2 Pet. 1:11), inheritance (Heb. 9:15), body (2 Cor. 5:1), and even judgment (Heb. 6:2, though cf. Mt. 18:8; 2 Th. 1:9, where the sense is perhaps “unceasing”).

CL The Gk. word αιων aion, which is probably derived from aei, … It thus appeared appropriate to later philosophers to use the word both for the dim and distant past, the beginning of the world, and for the far future, eternity (e.g. Plato, Tim. 37d).
Plato (Timoeus, ed. Steph. 3, 37, or ed. Baiter, Orell. et Winck. 712) says, speaking of the universe: …The nature therefore of the animal (living being) was eternal (aionios, before aidios), and this indeed it was impossible to adapt to what was produced (to genneto, to what had a beginning); he thinks to make a moveable image of eternity (aionos), and in adoring the heavens he makes of the eternity permanent in unity a certain eternal image moving in number, … And after unfolding this, he says (p. 38): "But these forms of time imitating eternity (aiona), and rolling round according to number, have had a beginning (gegonen).... For that pattern exists for all eternity (panta aiona estin on), but on the other hand, that which is perpetual (dia telous) throughout all time has had a beginning, and is, and will be." … Aion is what is properly eternal, in contrast with a divine imitation of it in ages of time, the result of the creative action of God which imitated the uncreate as nearly as He could in created ages.. ]
In Plato the term is developed so as to represent a timeless, immeasurable and transcendent super-time, an idea of time in itself. Plutarch and the earlier Stoics appropriate this understanding, and from it the Mysteries of Aion, the god of eternity, could be celebrated in Alexandria, and gnosticism could undertake its own speculations on time.

Aristotle peri ouranou, 1, 9 (ed. Bekker, 1, 279): "Time," he says, "is the number of movement, but there is no movement without a physical body. But outside heaven it has been shewn that there is not, nor possibly can come into existence, any body. It is evident then that there is neither place, nor void, nor time outside. Wherefore neither in place are things there formed by nature; nor does time cause them to grow old: neither is there any change of anything of those things which are arranged beyond the outermost orbit; but unchangeable, and subject to no influence, having the best and most independent life, they continue for all eternity (aiona). … According to the same word (logon) the completeness of the whole heaven, and the completeness which embraces all time and infinitude is aion, having received this name from existing for ever (apo tou aei einai), immortal (athanatos, undying), and divine." In 10 he goes on to shew that that beginning to be (genesthai) involves the not existing always, which I refer to as shewing what he means by aion. He is proving the unchangeable eternity of the visible universe. That is no business of mine; but it shews what he means by eternity (aion). It cannot be aidion and genesthai at the same time, when, as in Plato, aidios is used as equivalent to aionios
Philo, the sentence is in De Mundo, 7, en aioni de oute pareleluthen ouden, oute mellei, alla monon iphesteken. Such a definition needs no explanation: in eternity nothing is passed, nothing is about to be, but only subsists. This has the importance of being of the date and Hellenistic Greek of the New Testament, as the others give the regular, and at the same time philosophical force of the word, aion, aionios. Eternity, unchangeable, with no 'was' nor 'will be,' is its proper force, that it can be applied to the whole existence of a thing, so that nothing of its nature was before true or after is true, to telos to periechon. But its meaning is eternity, and eternal. … That is, things that are for a time are put in express contrast with aionia, which are not for a time, be it age or ages, but eternal. Nothing can be more decisive of its positive and specific meaning.

αιωνιος
• Strong's - Greek 165
• NRSV (the uses of the word in various contexts in the NRSV text):
again, age, course, end, eternal, forever, permanent, time, world, worlds
• CGED (A Concise Greek-English Dictionary of the New Testament, by Barclay M. Newman, New York: United Bible Societies, 1993, page 5):
age; world order; eternity (ap aion or pro aion, from the beginning; eis aion, and the strengthened form eis tous aion, ton aion, always, forever);
• The New International Dictionary of New Testament Theology [NIDNTT], Volume 3 (edited by Colin Brown, Grand Rapids, Michigan: Zondervan, 1978, page 827, 830):
In Plato the term [aion] is developed so as to represent a timeless, immeasurable and transcendent super-time, an idea of time in itself. Plutarch and other earlier Stoics appropriate this understanding, and from it the Mysteries of Aion, the god of eternity, could be celebrated in Alexandria, and gnosticism could undertake its own speculations on time.
The statements of the Johannine [John, 1 John, 2 John, 3 John] writings, … reveal a strong inclination to conceive of a timeless, because post-temporal, eternity… As in the OT [Old Testament], these statements reveal the background conviction that God's life never ends, i.e. that everything belonging to him can also never come to an end…
aion - αιων - age, world
A. "for ever, an unbroken age, perpetuity of time, eternity; the worlds, universe; period of time, age."
