To the dictionary's class of 1914: happy birthday!

'Backpack,' 'postmodernism,' and 'oy vey' turn 100

As 2014 draws to a close, lexicographers far and wide are carrying out their annual ritual of anointing the Words of the Year: Oxford Dictionaries' "vape," Merriam-Webster's "culture." But as the last days of the old year give way to the new, it's also our final chance to recognize another group of words: the ones that celebrated their 100th birthday in 2014, based on their first citation in the Oxford English Dictionary.

1914 was a propitious time for a word to be born. The outbreak of World War I on July 28 was bad for English-speakers, but good for English, said Katherine Connor Martin, head of American dictionaries at the OED. Conscription in the armed services, she said, meant "a lot of young people from very different social classes mixing, people from different English-speaking regions who are mixing, [with] people who speak other languages." This jumble inspired a vibrant military slang, which, along with names for new technologies in trench and aerial combat, trickled home in dispatches from the front—and in words like "trench coat" and "doohickey."

War wasn't the only force generating vocabulary that year. A number of new foreign slang and food words bear witness to waves of late 19-century immigration to America. (More sourly, offensive new terms for these ethnic outsiders also joined the dictionary, including "wop" for an Italian and "shonicker" for a Jew.) Sources as diverse as the criminal underworld and the argot of P.G. Wodehouse and James Joyce helped give rise to colorful slang terms, including a range of creative insults. A newly potent mass media—advertising, print culture, the world of Hollywood—propelled the creation of words like "advertorial," "blurb," and "movieland" that feel oddly modern today.

Many of the words turning 100 this year have died the unmourned death of "billiken" or "zingo." But others shape our daily speech. Where would we be without "posh," "backpack," or "oy vey"? Without "sociopath," "legalese," or "postmodernism"? Together these words offer a vivid portrait of our linguistic preoccupations one century ago—and some candidates ripe for revival in 2015.
