Usage notes
• 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
