Very clever vocab builder that is flash based. I only wish that it would have a built-in audio file for each word (I don't think I saw one -- could have missed it).
Fantastic web app to use for ESL classes because it is so much more than a traditional dictionary...
"What is Wordnik?
Wordnik wants to be a place for all the words, and everything known about them.
Traditional dictionaries make you wait until they've found what they consider to be "enough" information about a word before they will show it to you. Wordnik knows you don't want to wait-if you're interested in a word, we're interested too!
Our goal is to show you as much information as possible, just as fast as we can find it, for every word in English, and to give you a place where you can make your own opinions about words known.
By "information," we don't just mean traditional definitions (although we have plenty of those)! This information could be:
* An example sentence-even if we've only found one sentence for a word, we'll show it to you. (And we'll show you where the sentence came from, too!
* Related words: not just synonyms and antonyms, but words that are used in the same contexts. (For instance, cheeseburger, milkshake, and doughnut are not synonyms, but they show up in the same kinds of sentences.)
* Images tagged by our friends at Flickr: want to know what a "pout" looks like? We'll show you.
* Statistics: how rare is "tintinnabulation"? Well, we think you'll see it only about once a year. "Smile"? You might see that word many times, every day.
* An audio pronunciation-and you can record your own!
* Something YOU tell us! Use the "Contribute" links to tell us something-anything-about a word.
Visuwords uses a web design to show users the definitions of words and the connections between words. To use Visuwords just type a word into the search box and Visuwords will generate a web of related words. Place your cursor over any of the words and the definition appears. Use the color-coded key to understand the connections between the words in any web. Below is the web based on the word "geography."

Java.util package provides a Dictionary class which is the abstract parent of any class, such as Hashtable, which maps keys to values. Every key and every value is an object. In any one Dictionary object, every key is associated with at most one value. Given a Dictionary and a key, the associated element can be looked up. Any non-null object can be used as a key and as a value.
