I use that term lovingly....you know I love you and I am a grammar nerd also. I need to know when to use " versus ' For example.....doctor says to quote something that another doctor uses. Okay fine. I use "yada, yada yada." However, when he says: The radiologist did not use the term herniated disc. Would I use "herniated disc" or 'herniated disc' ?? I can't seem to find the way to use that symbol. Other than apostrophe, what would that (') be called?
