  • About dictionaries


    Check out also Dictionary.com Tools to install your dictionary in your toolbar.

  • Google


    When you include "define", "what is" or "what are" in your query in front of a word, phrase, or acronym, Google displays one Glossary definition above your search results. Google Glossary provides definitions for words, phrases, and acronyms that Google finds on web pages. The Glossary is good for finding definitions for terms that aren't in some dictionaries, e.g., slang words, technical terms, ethnic words and other specialized terms.
