The distinctive purpose of the present article is to single out those specific features of Nawat linguistic structure that are relevant to this language's general typological classification and characterization, answering the question: What major features make this language similar to or different from other languages? Most of the assertions in this article are generalizations from information found in the Pipil grammar article.
