Grammar Check is a feature that checks for grammatical mistakes in a document. Grammar Check can be useful in preventing embarrassing mistakes, but be aware that Grammar Check is not always right.
Grammar can be checked simultaneously with spelling. For more information, refer to Office 2003: Working with Spell Check.
Grammar Check can automatically check for errors in a document as you type. It can also be completed once you are finished with a document. When you turn this feature off, Spell Check will not run as you work on your document. The feature can be easily activated using the Options dialog box. You can also choose to have Grammar Check make suggestions about style.
From the Tools menu, select Options...
The Options dialog box appears.
Select the Spelling & Grammar tab
Under Grammar, select Check grammar as you type
From the Writing style pull-down list, select Grammar & Style or Grammar Only
Click OK
The automatic Grammar Check is activated.
When Grammar Check finds a sentence that appears to have improper grammar, the possible error will be underlined with a wavy green line. You can correct mistakes through the Quick menu or through a dialog box. If an error is without a clear solution, Word displays the grammatical rule being violated.
Using the Quick menu to access correction options allows you to manage grammar mistakes quickly and easily.
Right click the grammatical error » select the appropriate option:
| Quick Menu Option | Action |
|---|---|
| Suggestions | Corrects the error to the selected suggestion. |
| Ignore Once | Ignores only this instance of the error. |
| Grammar... | Opens the Spelling and Grammar dialog box, where you can choose from more options |
| About This Sentence | Opens an Office Assistant dialog box that explains the sentence error and suggestions. |
For more extensive editing, it may be more convenient to use the Spelling and Grammar dialog box. Using the dialog box option is a little more time-consuming, but you have more options for correcting possible errors. For information on correcting spelling errors, refer to Correcting Spelling.
From the Tools menu, select Spelling and Grammar...
