Each verb in natural language is associated with a set of arguments, which are not systematically predictable from the verb's meaning and are realized syntactically as the projected sentence's subject, direct object, etc. Babby puts forward the theory that this set of arguments (the verb's 'argument structure') has a universal hierarchical composition which directly determines the sentence's case and grammatical relations. The structure is uniform across language families and types, and this theory is supported by the fact that the core grammatical relations within simple sentences of all human languages are essentially identical. Babby determines and empirically justifies the rigid hierarchical organization of argument structure on which this theory rests. The book uses examples taken primarily from Russian, a language whose complex inflectional system, free word order, and lack of obligatory determiners make it the typological polar opposite of English.
