The Ngram Viewer Tool in Google Books is a useful tool for scholars, researchers, and anyone interested in studying the frequency of a word or phrase in human history. The tool allows you to search through a vast database of written material and create charts that show how often a word or phrase has been used over a certain period of time.

Step 2: Enter your search terms

Step 5: Interpret the results

After clicking the “Search books” button, the Ngram Viewer will display a graph showing the frequency of the searched term(s) over the selected time period. You can use this graph to interpret trends in the usage of the word or phrase, and compare it to other terms to gain insight into how language has evolved over time.
