Which claim states that grammar is built in and that people naturally develop a sense of grammar?

• A. LAD
• B. Universal Grammar
• C. Interactionist Theory
• D. Communicative language teaching

Answer: (B)

Universal Grammar is the idea that there is an innate, built‑in set of grammatical knowledge shared across all languages, and that people naturally develop a sense of grammar as they acquire language. This explains why children can pick up complex syntax even with imperfect input—they’re guided by preexisting internal principles and structures that shape how language is learned. The notion is distinct from a purely social or instructional approach, since it locates grammar as an inherent part of the human mind. The Language Acquisition Device is related, as a proposed mechanism that would access these universal rules, but the claim about grammar being built in and naturally developing aligns most directly with Universal Grammar. Interactionist Theory emphasizes social interaction in learning, and Communicative language teaching focuses on using language for communication rather than innate grammatical knowledge.
