We represent each word with the set of words that occur on the same pages as that word. We consider two words to be similar if these sets are similar, indicating that they occur in similar contexts. More similar words are shown in darker text. Years with no dark words probably have few instances of the query word.
Click or tap a word to highlight instances of that word (and words with similar prefixes).
Use this data with caution. These statistics are a good reflection of the language used in books selected by university libraries, but don't necessarily represent general usage. Digitization errors are frequent, and no attempt has been made to remove duplicate works.
