regulátora

A reguladora, in the context of Portuguese and Spanish linguistics, refers to a grammatical term used to describe a specific type of word or phrase that modifies or regulates another element in a sentence. The concept is most commonly associated with the study of syntax and semantics, particularly in the analysis of relative clauses and subordinate constructions.

In Portuguese grammar, the term "reguladora" is not as standardized as in other linguistic frameworks, but it can be loosely interpreted as a type of dependent clause that functions to restrict or specify the meaning of a noun phrase. For example, in the sentence *"A mulher que chegou"* ("The woman who arrived"), the clause *"que chegou"* ("who arrived") acts as a reguladora, providing additional information that narrows down the identity of "a mulher" ("the woman"). This type of clause is often referred to as a *restrictive relative clause* in English grammar.

The term may also appear in discussions about syntactic trees or dependency parsing, where it describes how certain elements in a sentence relate hierarchically. In some theoretical frameworks, such as Generative Grammar, reguladoras are analyzed as part of the broader study of phrase structure and how clauses interact within larger syntactic units.

While the term "reguladora" is not widely used in mainstream English linguistics, similar concepts appear under different names, such as *restrictive modifiers* or *determinative clauses*. Its usage is more prominent in Portuguese-language linguistics, particularly in academic or technical discussions about sentence structure. The precise definition may vary depending on the theoretical approach, but its core function remains tied to the regulation or specification of meaning within a sentence.
