Grammar Girl will help you improve your writing with this easy to understand guide. I have enjoyed Grammar Girl's website and podcast for years and this guide is a perfect reference to use at home, school or at the office. Words and phrases are alphabetized which make them easy to find in a hurry. I love the fact that famous quotes are used as examples. The hints on using plural forms and correct spellings were particularly helpful to me. I'm embarrassed to say that I have probably written donut and smokey before. Not anymore! I had fun reading this with my teenage son. We were both surprised to find that our grammar skills are not as good as we thought.
