Vocabulary is Fun Site (from the Creator of Spelling City!)

If you are an educator and don't know about Spelling City, take some time to check it out! I hadn't seen this Vocabulary is Fun site from the creator of Spelling City until Susan from Internet4Classrooms shared it with me this week.
This vocabulary site has games for students to build English vocabulary skills. Skills include analogy games, antonym games, contraction games, foreign language games, parts of speech games, prefix and suffix games, and many MORE!
Here is a description of their site:
Vocabulary is Fun is a leading vocabulary website worldwide with the best flash online word games. The vocabulary games include an online word search, an online crossword puzzle, and hangman online (our version is called HangMouse). Users choose the vocabulary list that the online word game will use in the word game. The vocabulary games are popular for use on smart boards for word games to build vocabulary skills in classrooms.
