What has happened to real words?

I had to go to webster.com to check when my bf told me they added words like selfie, hashtag and tweeter to the dictionary. seriously?!?!?!? these are all made up words. what happend to saying this is a picture of me? and what people are calling a hashtag is a freaking pound sign. and last but not least we all know that tweeter wouldnt even be around if not for twitter what happened to just saying im someone who writes my thoughts or a self published author

    Good question, Santana Ferrell! I have no idea but it seems like slang words have been added to the dictionary when I wouldn't be able to find them in my old high school dictionary.

      Alas, modern dictionaries are shouldered with the job of being descriptive rather than prescriptive--they can only reflect how the language is actually being used. Even the OED lists new words yearly, and they get odder each year. I think they sell more copies that way, lol.

        It really does and it is so sad. my kids will learn proper English and any word that i don't deem a proper word will get a sharpie through it in the dictionary. lol
