I have noticed that I hear "anyways" more and more often. This is NOT a word. "Anyway" is an actual word. I am surprised by how often I hear this. I even corrected our title agency rep once in order to help her seem more professional, because she was using "anyways".
Another interesting thing that I recently discussed with my wife - have you noticed that "I could care less" is used as much as "I couldn't care less"? Only one of them is correct, right? If you say that you could care less, it means you do care at least a little, and that is clearly not what is meant.
There are a lot of common grammar mistakes and misspellings in the MLS as well, such as "hugh" for "huge". Any others that you would like to share?
