Syntactic categories are classes of linguistic units defined by their grammatical distribution and structural behavior within phrases and sentences. They include lexical categories, such as nouns, verbs, adjectives, and prepositions, as well as functional categories, such as determiners, complementizers, and tense markers, depending on the grammatical framework adopted ^[1][2]. Syntactic categories are distinguished by the positions their members can occupy, the constituents with which they combine, and the grammatical patterns in which they participate; their classification and inventory may vary across linguistic theories ^[1][2].
