My Dictionary allows you to look up any word in an inline frame without leaving the page.

What does it mean?

My Dictionary is a Chrome extension that adds a simple pop-up box on any page of your browser.

After installing the extension, it automatically searches the source of the page, looking up the words you type into the search box.

The result is a box that displays the definition and examples of that word.

If you are using a version of the browser that does not support pop-ups, you can try to open the box directly. You can also click on any word to look it up in the dictionary.
