David Foster Wallace may be forever remembered as The Footnote Guy, and not without reason. His prolixity reached even into the small-print margins, and tempus tacendi never seemed to occur to him. Yet language was much more than unrefined fuel for the revving engine of his thought. Although he often got carried away with words, Wallace was keenly tuned to the way we use them, both on the page and in speech. You can find that sensitivity in his hilarious and sharp personal essay โ€œAuthority and American Usageโ€ (originally published in Harpers and then in his collection Consider the Lobster).

An even better place to get inside Wallaceโ€™s thinking as a writer is the Oxford American Writerโ€™s Thesaurus (Oxford University Press, 2004), for which he was a contributing editor (along with Francine Prose, Zadie Smith and other luminaries). Each editor offers โ€œword notesโ€ that pop up wherever a particular word provoked a thought. Wallaceโ€™s notes are especially useful and incisive, and he is neither a stodgy purist (explaining how the female connotations of โ€œeffeteโ€ are legitimate, both etymologically and historically) nor a postmodern linguistic scofflaw: His exegesis on the widely misused phrase โ€œbeg the questionโ€ is concise, eloquent and forceful.

Wallace is, of course, deeply aware of the political side of language, using a note at the word โ€œdysphesiaโ€ (a typo, amazingly: itโ€™s โ€œdysphasiaโ€) to swipe at Bush pรจre et fils. But he is also bluntly practical, which is ultimately what Wallace was always trying to be, I think. He lets you know, for example, that thereโ€™s no reason to use โ€œtowardsโ€ when โ€œusing โ€˜towardโ€™ is a costless, unpretentious way to signal your fluency in American English.โ€ And he wonders why anyone would choose โ€œutilizeโ€ (โ€œa puff-wordโ€), since โ€œgood-old โ€˜use’โ€ works just as well.

But perhaps the most revealing of Wallaceโ€™s word notes is for โ€œpulchritudeโ€: โ€œa paradoxical noun because it means beauty but is itself one of the ugliest words in the language.โ€ He lists some others (e.g. โ€œbig,โ€ โ€œcolloquialism,โ€ โ€œmonosyllabicโ€), and then suggests โ€œinviting your school-aged kids to list as many paradoxical words as they can [as] a neat way to deepen their relationship to English and help them see that words are both symbols for things and very real things themselves.โ€ That last observation is a beautifully condensed summary of the whole voluble, ugly, tiresome, self-obfuscating project of semiotics (so much for Wallaceโ€™s incorrigible prolixity). And now that Wallace is gone, his suggestion is a reminder that he died childlesshe was fantasizing about a fatherhood (and the accompanying life) that he never gave himself a chance to fulfill. Itโ€™s a terrible shame, because I suspect that Wallaceโ€™s kids would have been very lucky and very loved: A father who would tune me in to the nuances of languagewhich is our basic means of transit through all of our daysis a father I would have liked to have.
