" About 35-40% of the time, a player wants to create a word ending in a specific letter. This, however, is not the way we traditionally think, and, not to mention, this is not the way dictionaries are sorted. In other words, in many situations, conventional dictionaries are not arranged in an easy to use manner. This dictionary solves that problem by sorting on the last letter of the word. "
