CHAPTER 8 VARIATION IN SEMANTICS 8-] Introduction A discussion of variation in Aymara semantics must be based on an examination of what Hardman (in press a) calls the linguistic postulates of the language: categori- zations recurring at different levels of grammar and re- flected in cultural norms. An understanding of their nature and pervasiveness is needed in order to describe certain differences in their manifestations in different dialects (for example, in selectional restrictions on verb subjects and complements) especially to show differences between Missionary, Patr6én, and Radio Aymara on the one hand, and other Aymara dialects on the other (see Chapter 9).
