Through out this site you will find that almost every word is a clickable word thanks to free dictionary dot com. Makes the quest very easy and fun to continue knowledge in a rapid fashion. Just double click the word or words you want to lookup and a popup will come up and in that word in the definition you can click any of those words to continue on in the quest.
If the word is a part of a link it will just take you to the link but for the most part you should be able to click each word for the definition. Hope this is useful.
