Final answer:
The fastest way to search through a dictionary is to use the index.
Step-by-step explanation:
The fastest way to search through a dictionary is to use the index. The index will usually be located at the back of the dictionary and it contains a list of all the words in alphabetical order. You can quickly flip to the page where the word you're searching for is located. This allows you to find the word you're looking for much faster than if you were to search through the entire dictionary page by page.
