Feature 3
Elimination of inappropriate vocabulary
  • Words you don't want your children to use (insulting or attacking words, sexual words, words related to crime, etc.), words that aren't commonly used by children (words with difficult meanings, words without many chances for use), etc., are eliminated.

Removing a word eliminates it from the candidate terms and prevents it from being converted.
