How to Fix Spell Check in Word 2007

1. Hold down the 'Ctrl' key and press 'a' to highlight your whole document; making editions across the full document will ensure that they don't reset when moving on to other places in your text.
2. Click the tab labeled 'Review' at the top of the Word interface. This interface is called the 'Word Ribbon,' which groups common functions graphically instead of textually in menus, i.e., 'File,' 'Edit,' or 'View.' The Ribbon enjoyed expanded usage with the Microsoft Office 2010 package, meaning it's probably here to stay, so becoming competent with it is a must.
3. Select the 'Set Language' button on the Ribbon under the Review tab. Instead of opening a sub-menu as older versions of Word would have, it will bring up a dialogue box--a window which records your preferred settings.
4. Remove the check-mark from box next to 'Do not check spelling or grammar' if it exist there. There are other options under the 'Spelling' heading which may interfere with your spell check (there are options to not actively spell check, to ignore certain types of spelling, to ignore entries you have made to its dictionary, and more). Make sure your language is set to 'English' or whichever language you intend to type in.
