Today’s lesson is all about spelling mistakes involving adding an extra letter to a word, or accidentally removing a letter from a word. There are so many words in English where these errors can happen, but again I’m going to focus on the most common ones.
If you are looking for a quick way to check and correct your spelling and grammar, I recommend Grammarly - it's a free online tool! If you want to get personal correction from an English teacher, then I recommend joining our Advanced English Grammar Course or Reading Course, and selecting the option that includes teacher feedback.
