Subject-verb agreement helps establish structural dependencies and syntactic representations in language processing and acquisition.
The retrieved papers examine how subject-verb agreement functions as a core syntactic mechanism in language models and human language acquisition. Papers [3] and [10] directly address the grammatical and structural roles of subject-verb agreement. The remaining papers focus on agreement attraction errors, neuropharmacology, or unrelated multimodal tasks. Since the relevant evidence supports the claim and no papers refute it, the verdict is SUPPORTED.
