Even smart people make stupid mistakes in their writing.
Sometimes it’s laziness or impatience; sometimes they’re genuinely confused.
Using data from millions of its subscribers, Microsoft recently rounded up a list of the top 10 grammar mistakes in the English language. The findings come from people who use Microsoft Word and/or Outlook, both of which come with a tool called Editor.
Editor highlights spelling and grammar errors and makes suggestions to help improve your writing.
