The folks behind the Oxford Dictionary are asking you to help spread the word about its effort to Save the Words. According to the website SavetheWords.org:
Each year hundreds of words are dropped from the English language. Old words, wise words, hard-working words. Words that once led meaningful lives but now lie unused, unloved and unwanted. Today, 90% of everything we write is communicated by only 7,000 words. You can change all that. Help save the words!
This attractive and very well-designed website also has handy suggestions for you to help save the words in everyday life, including how to drop near-extinct words at board meetings and what to name your pet ("Cestuan," anybody?).
