what is difference between eternity and infinity
- æternity (archaic)
- æternitie (obsolete)
From Middle English eternyte, from Old French eternité, eternitez, from Latin aeternitās.
- (UK) IPA(key): /ɪˈtɜː.nə.ti/
- (US) enPR: ĭ-tûrʹnĭ-tē, IPA(key): /ɪˈtɝnɪti/
eternity (countable and uncountable, plural eternities)
- (uncountable) Existence without end, infinite time.
- (uncountable, philosophy) Existence outside of time.
- (countable) A period of time which extends infinitely far into the future.
- (metaphysical) The remainder of time that elapses after death.
- (informal, hyperbolic) A comparatively long time.
- In the sense “a comparatively long time”, eternity is always used with the indefinite article (an eternity).
- In philosophy, the common use of eternity to refer to an infinite time is considered incorrect, eternity referring to existence outside of time; existence within time but of an infinite temporal duration is called everlastingness or sempiternity
- (existence outside of time): atemporality, eternal now, extratemporality; see also Thesaurus:timelessness
- (infinite time): all time, perpetuity; see also Thesaurus:eternity
- (time extending infinitely far into the future): evermore, forever, foreverhood
- (remainder of time that elapses after death): afterlife; see also Thesaurus:life after death
- (comparatively long time): an age, ages, centuries, donkey’s years, hours, a lifetime, years, yonks; see also Thesaurus:eon
- (existence outside of time): sempiternity

From Old French infinité, from Latin infinitas (“unlimitedness”), from negative prefix in- (“not”), + finis (“end”), + noun of state suffix -tas.
- IPA(key): /ɪnˈfɪnɪti/
- Rhymes: -ɪnɪti
infinity (countable and uncountable, plural infinities)
- (uncountable) Endlessness, unlimitedness, absence of a beginning, end or limits to size.
- (countable, mathematics) A number that has an infinite numerical value that cannot be counted.
- (countable, topology, mathematical analysis) An idealised point which is said to be approached by sequences of values whose magnitudes increase without bound.
- (uncountable) A number which is very large compared to some characteristic number. For example, in optics, an object which is much further away than the focal length of a lens is said to be “at infinity”, as the distance of the image from the lens varies very little as the distance increases further.
- (countable, uncountable) The symbol ∞.
In mathematics there are several different infinities; see transfinite.
