An aeon is a stretch of time so long you cannot really feel it — far longer than a year, longer even than a lifetime stacked on a lifetime. Writers use it with a little drama: waiting felt like an aeon.

An aeon一個aeon is a stretch of time so long you cannot really feel it是一段長到你根本感受不到的時間 — far longer than a year比一年長得多, longer even than a lifetime stacked on a lifetime甚至比好幾輩子疊在一起還長。 Writers作家 use it with a little drama會帶點戲劇性地用它：waiting felt like an aeon「等待感覺像過了一個aeon」。

Scientists use it more strictly. In the study of the Earth, an eon (the same word, usually spelled that way in American science writing) is the biggest slice of history; several eras fit inside one eon. The spelling aeon is the older, more British look; eon is the usual American one. Both feel a bit literary in everyday talk.

Scientists科學家 use it more strictly用得比較嚴謹。 In the study of the Earth在地球科學裡, an eon (the same word, usually spelled that way in American science writing)一個eon（同一個字，美式科學寫作通常這樣拼） is the biggest slice of history是歷史裡最大的一個時間單位；several eras fit inside one eon好幾個era（代）都包含在一個eon（宙）裡面。 The spelling aeon拼法aeon是比較老式、比較英式的寫法; eon is the usual American one而eon是美式常見的寫法。 Both兩種拼法 feel a bit literary in everyday talk在日常對話裡都帶點文學味。

People are more likely to say ages or forever unless they want the extra weight. It is not a unit you can count on a clock. If you are talking about a few weeks, aeon is a joke or a stretch, not a careful use.

People大家 are more likely to say ages or forever比較可能會說ages（很久）或forever（永遠）, unless they want the extra weight除非他們想要那種加重的效果。 It它 is not a unit you can count on a clock不是那種可以用時鐘算的單位。 If you are talking about a few weeks如果你講的是幾個禮拜的事, aeon is a joke or a stretch用aeon就是開玩笑或誇張, not a careful use不是精確的用法。
