The 240,000-entry World Book® Dictionary is a powerful language resource for home, school, and business from the editors of World Book Encyclopedia.
This is the ultimate Mac dictionary. Don't try any of these things with the built-in dictionary in your Mac:
• Double-click any word in a definition to find out that word's meaning
• Give voice commands ("Pronounce please" or "Read the definition")
• Get a list of words with similar spellings (handy if you're not sure how a word is spelled)
• Check the history drawer with a list of words you have looked up during that session
• Pronounce each word you look up automatically (set in preferences)
• Click to have the definition read out loud from beginning to end
• Open multiple windows to compare definitions
• Choose colors for different parts of the definition (eg synonyms in red)
Our favorite feature, and soon to be yours, is "Related Entries". Let's say you look up the word "sand", you get the following choices for what to display in the Related Entries section:
• Found in Definitions: A list of words whose definitions contain the word "sand". For example, you would discover the word "sabulous" which means "consisting of sand; full of sand; sandy; gritty." Bet you didn't know that.
• Found in Examples: A list of words whose definitions page contains an example that uses the word "sand" in a sentence. For example, one word on the list is "pervious" whose definition contains this example: "Sand is easily pervious to water."
• Exact matches: A list of words in which "sand" appears, such as "sandal", "sandal tree" and "sandalwood".
• Similar words: A list of words with most of the letters the same. This is very handy if you are not quite sure how a word you are looking up is spelled.
Ratings and Reviews
Needs a thesaurus
As the dictionary packaged with Macs contains a thesaurus, and no thesaurus apps are currently available at the store, I cannot recommend this otherwise adequate dictionary.
Definitions Mediocre, No Thesaurus
The definitions in this dictionary are mediocre at best. When I buy a new dictionary I compare definitions I look up to various other dictionaries I own. This one had the worst definitions and no origin or derivation of the words. And nowadays I have come to expect a thesaurus to be built into dictionary applications, but this one doesn't have one. The dictionary that comes with every Mac OS is better than this one and has a built-in thesaurus. The spoken pronunciation feature is the only positive aspect of this application. If you need that then this app might be worth the cost. Otherwise save your money.
Dictionary is pretty good, but the voice ... weird computer voice.
Dictionary is ok, but the voice is obviously computer driven and the pronounciations are only a little helpful. I'm using it with the voice turned off.
With Family Sharing set up, up to six family members can use this app.
