Spelling

Editor.NET supports the spell-as-you-type spellchecker integration. To enable spelling for the editor, set its Spelling.CheckSpelling property to true and assign the WordSpell event handler.

Incorrect words are displayed with the wavy underline (the default color is red, but it can be changed using the Spelling.SpellColor property). In the production application you would need to use some third-party software to really check the text. Another alternative would be using some word-list file, many of them, including Public Domain or free ones, can be found on the Internet.
