In October 1937, the president of the Dominican Republic, Rafael Trujillo, devised a simple way to identify the Haitian immigrants living along the border of his country. Dominican soldiers would hold up a sprig of parsley—perejil in Spanish—and ask people to identify it. Those who spoke Spanish would pronounce the word's central "r" with that language's characteristic trill; the Haitians, on the other hand, would bury the "r" sound in the throaty way of the French. To be on the receiving end of the parsley test would be to seal, either way, one's fate: The Spanish-speaking Dominicans were left to live, and the Haitians were slaughtered. It was a state-sponsored genocide that would be remembered, in one of history's greatest understatements, as the Parsley Massacre.
Today, thankfully, the stakes of the shibboleth—the term gets its name from the Biblical story—tend not to involve such horrific matters of life and death. On the contrary, they tend to involve matters that don't much matter at all. To a large extent, modern-day shibboleths are status signifiers, the kind of loaded terms that reveal their utterers to be on a single side of a stubbornly binary line. They are not mistakes ("noo-cular" instead of "nuclear," "mis-chee-vee-ous" instead of "mischievous") so much as they are keys: They afford a kind of aural entry into arbitrary echelons. You know you've made it, for better or for worse, when you know that it's pronounced pee-kuh-TEE.
I mention all that because the Tumblr 454 W 23rd St New York, NY 10011—2157 has an extensive—and revealing (and occasionally, I'll admit, helpful)—list of "shibboleth words": words “by which,” the post accurately notes, “the privileged judge their inferiors.” The list consists mostly of names, most of which, in turn, belong to a Pikettyesque cadre of intellectual celebrities.
Like, for example:
Chinua Achebe (chin-oo-ah ah-chay-bae)
Roland Barthes (bart)
Walter Benjamin (ben-yameen)
Michael Chabon (shay-bonn)
Mihaly Csikszentmihalyi (me-high cheek-sent-me-high)
Paulo Coelho (~paw-lu co-ay-u)
J.M. Coetzee (~koot-zee-uh)
William Cowper (cooper)
W.E.B. DuBois (duh-boyz)
Michel Foucault (foo-coe)
Philip Gourevitch (guh-ray-vitch)
Johann Wolfgang von Goethe (~goo-tuh/ger-tuh)
Vaclav Havel (vat-slav hah-vell)
John Maynard Keynes (kanes)
Joan Miró (zhwan mi-roh)
Paul Klee (clay)
Anaïs Nin (ah-nayh-us ninn)
Chuck Palahniuk (pahl-uh-nik)
Jodi Picoult (pee-coe)
W.G. Sebald (zay-bald)
Slavoj Žižek (slah-voi zhe-zhek)
There are many, many more here. High-five yourself, or hang your head, accordingly. Meanwhile, if you want to impress people and/or not embarrass yourself at an upcoming Oscar party? It's Ralph Fiennes (raif), Lupita Nyong’o (~nnnnnyong-oh), and David Oyelowo (~oh-yell-uh-whoah). You're welcome.
