Can I hear each word pronounced?
Yes, by an opera singer! We've collaborated with New-York based opera singers to pronounce every word in our dictionary. Click the speaker icon to the right of any word to hear it pronounced. If a word has multiple pronunciations, we'll include multiple speaker icons as well as a chart in the right-hand column that will give you more information about when it's appropriate to use each pronunciation.

How does the Advanced Search work?
The Dictionary Advanced Search is a powerful tool to help you find just the right word(s) you need. It uses a series of parameters to help you discover, explore and refine your search. You can limit your search to parts of speech, display synonyms or antonyms of a word, restrict to a syllable range, find rhymes, or only show words that end with a certain letter or suffix. The Advanced Search can also pull words that contain a word or phrase in a definition. Additionally, you can search by type of (e.g. “flower” returns daisy, rose, peony), example of (e.g. “planet” returns Earth, Venus), and parts of (e.g. “computer” returns keyboard, microchip). After you hit the “Advanced Search” button, your results will be displayed below, and your search string will appear in the dictionary search field above. Try different parameter combinations for fun results.
