The variety of shape, pattern, and color found in the languages of the world is a testament to the wonder of nature, to the breathtaking array of possibilities that can emerge, tangled and wild, from the fertile human endowments of brain and larynx, intelligence and social skills. The job of the linguist, like that of the biologist or the botanist, is not to tell us how nature should behave, or what its creations should look like, but to describe those creations in all their messy glory and try to figure out what they can teach us about life, the world, and, especially in the case of linguistics, the workings of the human mind.

In libraries organized according to the Library of Congress call number system, linguists can usually be found in the stacks classified in the first half of the Ps, anywhere from subclass P, which covers general linguistics, to subclass PN, where “literature” starts. When I was in graduate school, I used to wander this territory, in a procrastinatory haze, noting how the languages covered by the intervening categories became more and more “exotic” the farther I got from PA (Greek and Latin). I would first pass through aisles and aisles of Romance languages, then Germanic, Scandinavian, English, Slavic. There at the end of the Slavic section, at PG9501, things would start to get interesting, with Albanian, followed by the offerings of PH—the Finno-Ugrics (Veps, Estonian, Udmurt, Hungarian), the mysterious Basque. By the time I got to PL, I would be far from Europe, drifting through Asia and Africa, lingering over A Grammar of the Hoava Language, Western Solomons or The Southern Bauchi Group of Chadic Languages: A Survey Report.

The final subclass, PM, was a tour through the New World, starting with the Eskimo languages of Greenland and Alaska and proceeding southward through Tlingit, Kickapoo, and Navajo to the Mayan and Aztecan languages of Mexico and Central America, down across the Amazon, through the Andes and the plains of Brazil, until I reached the islands off the southernmost tip of South America with Yámana-English: A Dictionary of the Speech of Tierra del Fuego.
