Do environmentalists fall asleep to dreams about fields of Iowa corn filling up the tanks of station wagons? What about NASCAR drivers? Maybe they do, if recent advances in technology--and the popular buzz that follows--are any indication. That is why the 2007 Word of the Year at Webster's New World College Dictionary is grass station. The term is so hot that it already has appeared on the op-ed page of The New York Times.

Grass station, a pun on gas station, refers to a theoretical fill-up spot in the not-too-distant future; it reflects America's growing love affair with hybrid cars and vegetable-based fuels (and words), including ethanol and biomass fuels--some of which really are distilled from plain old grass--note Webster's New World editors who chose the term from more than 2,000 finalists. "Webster's New World editors and researchers constantly collect examples of emerging English--some 2,000 new examples per month--and choose one word or phrase that captures our imagination," explains Editor-in-Chief Michael Agnes.
