In Illustrator, you can use the spell checker to help you correct your spelling. To use the spell checker, open the file that you want to check and click on the Spell Check button. The spell checker will start checking your text and will give you feedback about how well it is spelling words. You can also choose to have the spell checker work on all of your files or just a specific file. After it has checked all of your text, it will give you a list of errors that it found. You can then fix any of these errors by clicking on them and then clicking on the Fix button.
