Thank you for the interest.

  1. The default dictionary is a public domain Webster’s dictionary from 1913. (Therefore the defintions are often somewhat antiquated.)
  2. A word is flagged if its frequency of occurrence is less than 10^-(6.3+level/100). For example, a level 0 word occurs once in every 2 million words whereas a level 100 word occurs once in every 20 million words.
