Expanding Dictionary

All of you word lovers will be happy to know that Merriam-Webster has added a bunch of new words to the dictionary. While these words have been around for a while, they have to gain sufficient popularity to actually get added to the dictionary. Some of my favorite additions are:

• mental health day (I'd like to think that my former colleagues and I helped popularize this one!)
• air quotes
• racino
• subprime (an unfortunate addition)
  
• wing nut (This poor word has been around for over 100 years and is only just now being recognized as legit!)
