The Dutch, French, German, and Turkish lists were generated by expanding the source dictionary’s affix rules, removing punctuation and entries outside the supported alphabets, keeping words of 2–15 letters, normalizing Unicode and letter case, and removing duplicates. These adapted lists retain their respective source licenses.

Original dictionary files and affix rules are included below. The editable download includes the generation script, which uses the MIT-licensed nspell library. English is unchanged.
