QUESTION MARK OVERVIEW
Question marks are fairly straightforward and are used in English (and many other languages) to indicate that a question is being made. The only real trick to learn with question marks is to know that they can–in some instances–be used in the middle of a sentence, not just at the end.
Question Mark difficulty ranking: 13/14 (really easy to master!)
Question marks aren’t hard to learn–you’ve been using them since kindergarten. But recognize that you can insert them in the middle of a sentence (especially in parentheses) in order to clarify and give variety to some sentences.
