Is it acceptable to serve edamame to a dinner guest who’s a pescatarian?

Should you pour prosecco or soju for the winner of the Texas Hold ’em game you’re planning near the infinity pool? And what’s that wing nut in the corner saying about dirty bombs and nasty Noroviruses?

Before your next party, go ahead and consult the latest edition of Merriam-Webster’s Collegiate Dictionary, which now includes edamame (immature green soybeans), pescatarian (a vegetarian who eats fish), and about 100 other newly added words that have taken root in the American lexicon.

The wordsmiths at the Springfield, Mass.-based dictionary publisher say they picked the new entries after monitoring their use over years.

“As soon as we see the word used without explanation or translation or gloss, we consider it a naturalized citizen of the English language,” an editor-at-large for Merriam-Webster, Peter Sokolowski, said. “If somebody is using it to convey a specific idea and that idea is successfully conveyed in that word, it’s ready to go in the dictionary.”
