Morphosyntactic processing refers to the cognitive operations involved in identifying, integrating, and interpreting morphological information and syntactic relationships during language comprehension and production ^[1][2]. It includes the processing of grammatical features such as tense, number, gender, case, and agreement, as well as the construction of syntactic structures that organize words and phrases into meaningful expressions. In psycholinguistics, morphosyntactic processing is examined through the time course and mechanisms by which language users access grammatical information, establish dependencies among linguistic elements, and resolve grammatical ambiguities during real-time language use ^[1][2].
