We asked users to submit instances when they hear a new word (not new to them, but new to the language), and the place where they heard the word. The end result was an interactive, evolving map that visualizes how the use of new words or phrases spread from one place to another. As language is a reflection of the cultural zeitgeist. Word Chaser was not only a linguistic tool that helped trace the etymology of new words, but also a description of the cultural character of different neighborhoods.
