Help: Using TheFreeDictionary

TheFreeDictionary's content is divided into tabs. Each tab represents search results from a different dictionary or encyclopedia. You can see the results of your search in different dictionaries by switching between the tabs.


The Dictionary/Thesaurus tab is the default tab. When you begin a search on TheFreeDictionary's homepage, you will see results from the Dictionary/Thesaurus.

Page Tools

You can cite the results in a research paper, add a link to the results in a web document, or email the results to yourself or to a friend. You can also use this section to leave us feedback.


This shows you how to cite an article in the proper MLA, APA, and Chicago formats. This tool is tab-aware, meaning it knows which tab you are citing information from; in the Dictionary/Thesaurus tab, the cite option shows the citation format for both the dictionary and thesaurus sections. The link option gives both the page URL and the HTML link information, which helps webmasters link to our information from their sites.
