In Classifier Structure in Mandarin Chinese, Niina Ning Zhang proposes a new approach to the count-mass contrast, and the properties and functions of classifiers when they occur with numerals, with various quantifiers, in compounds, and in reduplicative forms. The new approach makes a significant contribution to our understanding of the existence of classifiers in numeral classifier languages. The investigation also uncovers that certain non-classifier languages lack only one type of classifiers, whereas other non-classifier languages may lack other types of classifiers.
