Lists for Writers now has definitions available (for iOS 5+)! This has become a frequently requested feature. Now you can tap on any word in a list and get the definition for it*.

We’re excited about this new feature and it’s already proven useful.

This update also adds a new list of body types and improves our support for older devices. The iPhone, iPhone 3G, and iPod Touch second generation and older should all now be supported as long as they are running iOS 4.0 or higher.

* Not all words in the app appear in this dictionary, but most of those appear on lists that already contain a definition.
