Free, straightforward, and attractive, Dictionary.com for iPhone and iPod Touch has one or two highlights that give it some interest beyond searching for a quick dictionary definition. It isn't the only dictionary application for iPhone by a long shot, but it is a solid effort that has brand name appeal for Internet vocabulary geeks--plus, it's got those helpful tidbits we mentioned. For instance, after typing a search term, you can switch between the dictionary definition and thesaurus without losing your word. Also, the definitions and synonyms are preloaded into the app, which means your world of words won't go dark if you lose Wi-Fi or signal. Unfortunately, it also means there's a lengthy installation wait.
With an intact data connection, the app can read your definition aloud. Logophiles who want more vocabulary excitement can tune into the Word of the Day feature on the phone, and will be prompted to sign up for the e-mail definition delivery service as well.
The iPhone app is missing some of the power behind Dictionary.com on the Web--most notably, the translator and helpful articles. As a search-and-retrieve word application, however, this is a good start for those looking for a free reference app or who are trained to prefer Dictionary.com's experience.
