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 data comes 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.
It can make a bad impression if you have a document riddled with mistakes, says Nicole Michel, a linguist who is also a project manager at Microsoft.
She told Business Insider: “If you send a CV to a potential employer and it’s full of grammar or spelling mistakes, it’s going to show carelessness and lack of attention to detail, and also it shows that you’re not really putting emphasis and importance on the task.”
