Three Little Words: A, An, and the (A Foreign Student's Guide to English Articles) (A Foreign Student's Guide to English Articles) (A Foreign Student's ... Foreign Student's Guide to English Articles)

As an ESL (English as a Second Language) instructor, I think this book is a godsend. It chronicles all the nuances of article usage beyond count vs. noncount nouns, which cover only some, but not all, of the reasons for articles. After explaining that singular count nouns MUST have articles, students are still stumped on other occasions. For example, some ailments take an article while others don't. Why is that? This book answers that and many more.
