If you need to look up a word during your session, click the Dictionary link in the toolbar (found in the banner area at the top of the page). You'll see the Dictionary look-up page in a separate browser window where you can search for a word in the online Merriam-Webster Collegiate Dictionary.
Enter a word, or just the first several letters and then click Search.
If what you enter matches a word in the dictionary, you'll see the page of the dictionary where the definition or definitions are found.
If what you enter doesn't match a word in the dictionary, you'll see words that alphabetically follow what you entered. You should be able to find the correctly spelled word either on the page you see first or on a nearby page, using the Previous and Next arrows to page through the dictionary. To look up a new word, enter it the input box and click GO.
To look up a word from a screen in this database, highlight the word, then click on the Dictionary link. The definition will be displayed, along with the next words that appear alphabetically after it.
