That picture above is an index of page numbers with words I didn’t know in Infinite Jest. So basically, I just added more information to a whopping book of information. I’d be curious to know how many of these words you guys know, and whether other readers of IJ kept a similar list. One of the pleasures of reading the book for me was keeping this list and discovering that such varied bits of existence had such specific words to name them. Looking through a copy of Both Flesh and Not, which has Wallace’s essays separated by two pages of his vocab words, brought back a pretty warm memory of how much fun it was to read IJ‘s sentences.
Before we begin, some thoughts:
It should be noted that this list doesn’t include most of the hyper-scientific or hyper-medical terms because, well, I think my head would’ve blown a gasket.
Something you might notice: “agnate” is on here three times. That’s because I didn’t know “agnate” on page 91 and when it came up again on page 151, I still didn’t know it, and when it came up again on page 382 as “agnation,” I still didn’t know it. (Same thing happened with “scrofulous.” And “saprogenic.” And “lordotic.”) In that way, I suppose the title of this post is a lie.
Nonetheless, below you’ll find some pretty difficult vocabulary. If you want to know the most difficult passage of the book, my vote would go to pages 322-333, in which the details of Eschaton are laid out (which was supposedly Wallace’s favorite part of the book). If I had to estimate, I’d say those 11 pages took me an hour and a half to read.
One last note: my spellchecker is telling me that 129 of these words aren’t real words.

What a fun article. I was going to comment that I know quite a lot of those words, but some I know only because I looked them up back when I read IJ. Others are words that those of us over age 60 didn’t realize might be uncommon today. Others are common words for those of us who have studied speech, those who have encountered various medical conditions, and those who looked up the same words when we were reading Pynchon. Thanks, Gabe, for daring to expose your own list–mine would be different (though overlapping), but would be at least as long.
I loved reading this–I hadn’t realized how many medical terms DFW uses in IJ until now. I appreciate your honesty about which words you didn’t know.
Nothing better than starting a new book and realizing you will need to keep a dictionary nearby!
“Aphasia” is in there a couple of times too. Along with “aphasiac”.
For what it’s worth I know 110 of the words, but then I’m over 60 and had a classical liberal arts education and like to read popular science and math books.
Oops, I mean to say that I know 150 of the words.
20. The first instance of “amanuensis” is spelled wrong.
141. As a noun, “matins” is always pluralized. “Matin” singular is the adjective.
183. “Whinge” is the British synonym of the American “whine.”
Thanks, this was fun!
One of my pleasures in unusual words is the way they can recall the context in which I first read them: lordosis, for example, from Willie Keith’s navy physical exam early in Herman Wouk’s THE CAINE MUTINY; and nacelle from descriptions of the original Starship Enterprise.
Word lovers who haven’t read Anne Fadiman’s “The Joy of Sesquepedalians” (in her essay collection EX LIBRIS) should definitely acquire a copy.
The Roman general is likely not the reference intended for “luculus.” I wrote an article about this which you can read here:
http://www.jgoodwin.net/academic/papers/wallace-ij.pdf
I would guess that you are either under the age of 30 or have by-passed a liberal arts education. At least a quarter of these words are present in the vocabulary of those over 50 and/or those who have had the benefit of a liberal curriculum. But, I applaud the effort you put into identifying and researching the words. Commendable, and useful means of acquiring knowledge.
I applaud Gabe for subjecting himself to the high probability of comments like this being made. I certainly didn’t keep an extensive vocab list when I read IF, and probably should have it I wanted to appreciate it to the full potential. I’ll keep this list in mind if ever I feel the need to return to IF.
P.S – Eschaton most certainly my favorite too
UMmm…on what planet? I’m an educated man who is turning 50 this year and I too had to take my reading a bit further when diving into Infinate Jest.
There is a fair number of well-known words in there; I agree with the 25% estimate. But I have to ask: what happens between the ages of 30 and 50?
Actually, upon rereading, I’d say the percentage of widely-known words is closer to 40%. But then again, I work with words for a living!
Looks like somebody’s got WAY too much time on their hands….
