Why is this called Ninjawords?

Ninjas are three things:

  1. They're smart
  2. They're accurate
  3. They're really fast

Ninjawords is based on these principles.

How do you pack so much awesome into that little text box?

Ninjawords is optimized to return a definition instantly as soon as you hit enter, and your search is spellchecked in multiple ways until we find a good match. Ninjas like to stay lean and mean, which is why there is no junk cluttering your dictionary, slowing you down.

All definitions come from the ever-expanding Wiktionary data set.
