Query: Has its merits, but doesn't explain enough

I had to use this book for French 101 in college. I don't recommend it, if you're not being forced to purchase it. The culture sections do contain a lot of helpful and interesting information about France and the other French-speaking countries, but the book has a nasty habit of not explicitly defining the vocab words it introduces. Many of the nouns come in the form of little drawings, with the French underneath. If the picture is unclear (which they tend to be), you'll have to check the French-English dictionary in the back. Most of the words they use are there, but not all of them. In those cases, grab a bigger dictionary or Google Translate. I got my book used, and the person who I bought it from wrote many of the translations next to the words, which helped me out a lot.I understand that a foreign language textbook can use words that it doesn't explicitly define, but it shouldn't be doing it when introducing the basic chapter vocab words.
