1) Covering all the layers of the sentence right periphery in Chinese, eight sentence-final particles and the interaction among them are comprehensively studied. 2) Through the lens of feature theory, the theoretical views from a variety of dimensions are discussed. 3) It allows us to see how L2 learners whose first language has no similar equivalents acquire these peripheral particles. 4) With its commonly used nature in spoken Chinese, both the linguistic analysis and the findings from the empirical studies of the particles in this book are significant for learning and teaching of Chinese.
