Here is a context clues worksheet on the noun epoch. As I recall, I wrote this because the word kept popping up in a global studies class I co-taught in New York City some years ago. I wanted to make sure students fully understood the meaning of this word.
In any case, it remains in sufficiently common use in English that it is worth teaching for its own sake.
