Lost in the hubbub about the new words and disappearing hyphens in the latest edition of the Shorter Oxford English Dictionary is a more subtle type of editorial revision. The Shorter, as a dictionary built on historical principles, provides information about the age of words and their main senses. The date range of earliest known use is noted in each entry by E (early), M (mid), or L (late) plus a century number: thus “M18″ means a word was first recorded in the mid-18th century. This style of dating is admittedly approximate, but giving the exact year of a word’s first recorded use would lend a false sense of precision. We very rarely can determine the first “baptismal” usage of a word with any confidence. But even with dates given by rough century divisions, the editors of the Shorter have been able to revise the dating of nearly 4,500 words and senses based on discoveries of earlier recorded uses, known as “antedatings” in the dictionary world. Much of this new antedating information is derived from the ongoing work done for the third edition of the Oxford English Dictionary. Since I dabble in what my colleague Erin McKean recently called “the competitive sport of antedating,” I thought I’d share a discovery of mine that made it into the new edition of the Shorter.
