Abstract: This paper investigates the distribution of individual denoting nouns and substance denoting nouns in Mbyá (Tupi-Guarani), with respect to plural marking, numerals and quantifiers. The study reveals the existence of a robust grammatical distinction between a class of count nouns, populated mostly by individual denoting nouns, and a class of mass nouns, populated mostly by substance denoting nouns.
