Google has introduced a new advanced search command that is designed to enable users to find the most current definitions to word(s) and phrases. Users can type the word "define," then a space, and the word or phrase they want defined into the Google.com search field. If Google has seen a definition for the word or phrase on the Web, it will retrieve that information and display it at the top of the search results page.
For instance, someone looking for the definition of "search Engine" can enter the words [define search engine] and will be presented with a list of current definitions. Because Google Glossary definitions are collected from the Web, Google Glossary can find definitions for contemporary and/or obscure words and phrases that might not have yet made it into other dictionaries.
Google Glossary results are highlighted as "Web Definition" followed by the text of the Web-generated definition. If Google has more than one definition, users are presented with a link marked "more definitions" for a complete list. In addition to the "define" search command, the words "definition," "what is," and "what are," when placed before the query, will also trigger a Google Glossary result. All Google search syntaxes such as the phrase search (a query surrounded by quotation marks) can be used with these Google Glossary commands.
Google Glossary is available now on Google.com to all English language users. International versions will be made available in the coming months. Google Glossary is also available to users as a stand alone service via Google Labs at labs.google.com.
