To celebrate National Dictionary Day on Oct'16 -- which honors Noah Webster, often regarded as "the father of the modern dictionary" -- you might like to take advantage of this classic word widget, which provides quick access to some of the more traditional areas of Wolfram|Alpha's lexicographical data: definitions, pronunciations, synonyms, and more for most English words.
Or grab the next widget if you want to play around with a few of the "fun" features, including the ability to compute anagrams and convert words to telephone keypad digits. One of the menu items here, which lets you find city names containing a given word, is actually a subset of a much larger new feature. Whenever Wolfram|Alpha provides general data about a word, it now displays a sampling of other things in its knowledge base that contain that word -- movie and book titles, given names and surnames, mountains, lakes, rivers, and more.
