The present research describes non-nuclear predicates that modify the nucleus of the matrix clause, the clause or its constituents. The non-nuclear predicates show grammatical properties of their own. In order to make this explicit, data from the Mazahua language are presented in order to warn that these are not complex constructions, but simply modifiers, considering that the language presents any grammatical category as the nucleus of the predicate. From the set of non-nuclear clauses, it is proposed that they can be realized as coverbs, operators, adverbial property predicates, adverbial temporal predicates and juxtaposed direction predicates. The research concludes that non-nuclear predicates are neutralized in person and time, lack argumentative structure, have no internal modifiers, belong to a closed class, acquire specific positions, maintain a juxtaposition relation and perform ...

The article presents the set of morphemes that are anchored on the nucleus. The informative and grammatical content of the clause has been distributed in prosodic phrases. The position of the morphemes that expresses grammatical functions within the verbal domain indicates whether they are enclitics or proclitics; thus, those that are located to the left of the verb are realized as operators, and those that are located to the right encode grammatical information. The article proposes that grammatical features such as polarity, modality classes, quantification types, movement forms, aspectual and temporal values are operators; clitics appear individually or in a cluster. Clitics is restricted by prosodic criteria; it presents fixed positions; it does not duplicate; it does not exhibit cumulative values; it occurs with different semantic value; only some meanings of the same group covary s...
