SIGHTSEEING: A listener asked, “Why is it sightseeing and not siteseeing? Aren't you seeing sites? Sightseeing sounds redundant.” Interesting question! ON ACCIDENT or BY ACCIDENT: A listener asked, "What is the deal with the term on accident? I've always used by accident, but I've noticed a lot of pretty smart people . . . I've noticed them using on accident. So, am I wrong?" Sometimes when I get questions like this I can't find an answer, but in this case, I hit pay dirt! I was lucky enough to find an entire research paper on the topic.
