HOW TO USE THE DICTIONARY

To look up an entry in The American Heritage Dictionary of the English Language, use the search window above. For best results, after typing in the word, click on the “Search” button instead of using the “enter” key.

Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you type them in the search bar. For best results with compound words, place a quotation mark before the compound word in the search window.

Indian Territory

A region and former territory of the south-central United States, mainly in present-day Oklahoma. It was set aside by the government as a homeland for forcibly displaced Native Americans in 1834. The western section was opened to general settlement in 1889 and became part of the Oklahoma Territory in 1890. The two territories were merged in 1907 to form the state of Oklahoma.

Thousands of entries in the dictionary include etymologies that trace their origins back to reconstructed proto-languages. You can obtain more information about these forms in our online appendices:
