As a child, I hated the answer “Because” when I asked the question “Why?” It’s a non-answer answer that imparts no information and implies that the matter is closed.
As an adult, I teach editing and writing, and work individually with students who need help in both. They have lots of questions — good questions — about why English is the way it is. And, unfortunately, the simple answer to many of those questions is “Because.” (In fact, many of the questions have complicated answers based on when words entered English, where they came from and when their forms were standardized, but those answers don’t fit neatly in a sentence or two, so I’m left with a choice between 10 minutes of explaining or “Because.”)
