aeon
永劫
覚え方のコツ Memory Tip
aeon は eon の英国式つづりで、「一時代」または想像できないほど長い「永劫」を表します。先頭の ae を一まとまりとして捉え、発音は通常 eon と同じです。for aeons「何世代にもわたるほど長く」や geological aeon「地質学上の累代」の形で、日常の誇張表現と専門用法を区別して覚えます。
Treat aeon as the chiefly British spelling of eon; the two forms normally have the same pronunciation and meaning. The opening ae may look unusual, but it preserves the word’s Greek and Latin spelling history. Imagine a timescale so large that ordinary centuries seem tiny. In everyday language, for aeons exaggerates how long something has lasted, while in geology an aeon is a formal, very large division of time. This contrast between vast informal time and precise geological time makes the word easier to place correctly.

aeon の語源・成り立ち Etymology
ギリシャ語 aiōn(時代、生命、永遠)に由来し、ラテン語 aeon を経て英語に入った。「長大な時間」を意味する語根で、関連語に eon(同義の略式表記)、eternal(永遠の)がある。地質学的な悠久の時を表す語根と覚えると意味がつかみやすい。
Aeon comes from Greek aiōn, a word used for an age, a lifetime, or a long span of existence, and passed into English through Latin aeon. The spelling aeon retains the traditional ae sequence, while eon is the simplified and now more common variant. Its history accounts for both the broad sense of an immense period and its specialized use in geological chronology.
