Houghton Mifflin give this list of one hundred words that every high school graduate ought to know:
I take them to mean that every high school graduate should aspire to incorporate these words into their vocabulary, not that every graduate should be expected to already have an adequate command of them.
Irritatingly, I missed four:
- “evanescent” (quickly fading or disappearing)
- “fiduciary” (involving trust, particularly a relationship)
- “moiety” (a distinct part into which a thing can be divided)
- “pecuniary” (involving money)
For more adventures in sesquipedalianism, I suggest Eugene Ehrlich’s The Highly Selective Dictionary for the Extraordinarily Literate.

It’s highly amusing that “impeach” is on the list. :)
