The red wavy line indicates Microsoft Word thinks the word you've typed is misspelled, or that you've inserted a proper name or jargon not in the Word dictionary. If you see a green wavy line, the application thinks you've used bad grammar.
You can turn these features on and off under the Tools menu: Spelling and Grammar, Options. Notice the first item under Spelling says, "Check spelling as you type." When this box is ticked, the application checks spelling in real time and notifies you of (suspected) errors by placing a red, wiggly line under the word. If you find this annoying, you can turn it off by un-ticking the selection box. This is also true of the green squiggly line generated by the grammar checker.
Green wavy underline indicates grammar "mistakes" (you have to turn the grammar correction function on to have Word indicate it has found mistakes)
