Biodiesel has hit the big time – it’s in the dictionary now. The National Biodiesel Board is pleased that the word “biodiesel” appears in the 2006 update of the Merriam-Webster’s Collegiate Dictionary, Eleventh Edition . This marks the first time that it has appeared in the dictionary, and signifies that biodiesel is becoming a household word. What’s more, word has it that Merriam-Webster put biodiesel on the short list of examples of new words added to the dictionary. That means “biodiesel” joins the ranks of “ringtone,” “soul patch” and “supersize” in drumming up interest in modern lexicography.
