Just like facts and flies, English words have life-spans. Some are thousands of years old, from before English officially existed, others change, or are replaced or get ditched entirely. Here are 18 uncommon or obsolete words that we think may have died early. We found them in two places: a book called "The Word Museum: The Most Remarkable English Words Ever Forgotten" by Jeffrey Kacirk, and on a blog called Obsolete Word of The Day that's been out of service since 2010. Both are fantastic- you should check them out.
