Google's Define Operator, No Longer Useful

Last month, Google added a new search options in the sidebar: dictionary. It's a new interface for Google Dictionary that combines definitions from a reputable dictionary with definitions from the Web, usage examples and other useful information.

At the same time, some users reported that Google's define: operator no longer works. The operator was useful to find definitions obtained from Web pages, so you could type [define:iffy] and find a list of definitions. Now the operator is no longer broken, but it only shows the definition from Google Dictionary and links to the dictionary page. You could type [define iffy] and get similar results.


Maybe Google should send users to the dictionary page when they use the define: operator. It's an advanced feature that's not used by many people, but it's very useful.

Here's how it looked:

Google Tests a Search Option for Definitions

Google experiments with a search option that lets you find the definition of a word without using the define: operator or adding "definition" to the query. Selecting the "dictionary" option from the sidebar doesn't restrict the results to sites like Dictionary.com and Answers.com, but shows the information that's available in Google Dictionary. To be fair, Google includes a section called "web definitions" that shows definitions from Wikipedia, WordNet and from different glossaries.


This feature is not yet available to everyone, but you can always install extensions like Google Dictionary for Chrome, Google Dictionary and Google Translate for Firefox or add Google Dictionary to your browser's search engines.

Google Dictionary Has a New Content Provider

Google's English dictionary switched from the Collins COBUILD Advanced Learner's English Dictionary to the Oxford Pocket Dictionary of Current English. The definitions from the Collins dictionary are easier to understand, while the Oxford dictionary is more traditional.


Here are two definitions of the word "swot":

Collins: "If you call someone a swot, you disapprove of the fact that they study extremely hard and are not interested in other things."

Oxford: "A person who studies hard, esp. one regarded as spending too much time studying."

Google's New Dictionary OneBox

Google added a new OneBox result for definitions. The OneBox uses data from Google Dictionary, shows pronunciation information, short definitions and links to other reference sites like Dictionary.com and Answers.com. Google shows the definition of an English word only if it's likely to be useful, so you'll usually see the OneBox when you search for obscure words or technical terms.


"We added implicit triggering, which means you can simply search for [flummox] and find the definition, you don't have to search for [define flummox] or [what is flummox]. We've also improved the definition result snippet to show more details such as parts of speech and pronunciation," explains Google.

Unfortunately, Google's new OneBox is redundant and inconsistent. If you type [salient] in Google's search box, Google Suggest already shows a definition of the word from Princeton's WordNet.


Search for [define salient] and Google shows a definition from WordNet, not from Google Dictionary.


Tip: to trigger the new OneBox when it's not displayed by default, add en:en to your query. For example, search for [en:en emulsion].

New Format for Google's Definition Results

Three months ago, I found some Google search shortcuts that trigger results from Google Dictionary and Google Translate. The keywords for Google Translate no longer work, but you can still add "en:en" before an English word to see the definition from Google Dictionary.

Google's results now include links to Wikipedia, Dictionary.com, Merriam-Webster and Answers.com. Two of these sites (Dictionary.com and Answers.com) have been previously used to show definitions for each word of a query. They have been replaced by Google Dictionary and the feature has been removed when Google launched a new interface, two months ago.

Here's an example of query that triggers the special definition results: [en:en overcast].


Google has another special result that's displayed if you search for [define word] or [word definition]. This time, Google shows definitions from WordNet.


There's also a define: operator that shows definitions from WordNet, Wikipedia, glossaries and other web pages.
