Using spell check in Word can prevent errors from appearing. Use the Word spell check function to produce error-free Word documents.
Not only does Word allow you to Undo possible mistakes in your document and Paste corrections, but it also automatically reviews your grammar and spelling as you type. Green wavy lines are placed underneath possible grammar mistakes, while a red wavy line goes under possible spelling mistakes. All of Word's grammar and spelling errors may not be correct, so you can choose to ignore these error markings and keep typing, or you can correct the mistakes and/or add the corrections to Word's dictionary.
