Meaning two stumps me. A book or movie trailer is a preview that comes before the book or movie. Why? Shouldn't it be called a preceder because it comes before? I would think a 'trailer' for a movie or book should come after it. Has anyone ever said: Hey, that movie was great, we should go watch the trailer now! Well, I suppose in some cases the trailer is better than the actual film, but I digress.
What is my point, you ask? Simple: If it comes before, it should be known as a preceder. If is comes after, it is a trailer. So, feel free to take a look at my book preceder on my Books page.
