Query: Excellent resource for both beignners and more advanced learners

Claudia Ross improves and expands the work she did forSchaum's Outline of Chinese Grammarwith a thorough and easy-to-use grammar guide for both beginning and intermediate learners. Chapter titles separate the language into clear and concise entires that are easy to navigate and provide hundreds of example sentences. "Modern Mandarin Chinese Grammar" is exhaustively cross-indexed by chapter number to help learners distinguish between multiple uses of the same word/character. Overall, an excellent resource for serious students of the language!Nathan Dummittauthor ofChinese Through Tone & Color
