What is dictionary guide words?

Dictionary guide words are the words located at the top of each left and right page of a printed dictionary. They serve as a guide to quickly find a word in the dictionary by showing the first and last words listed on each page. For example, if you are looking for the word "apple," you simply need to find the page where the guide words start with "app" and end with "apt" to locate the word "apple." Dictionary guide words are especially helpful for people who need to find a specific word quickly, such as students, researchers, and writers. They are also commonly used to teach alphabetical order to children.
