Which concept is described as an inherent blueprint or template for language structures to explain why disabilities develop?

• A. LAD
• B. Innateness Hypothesis
• C. Transformational Grammar
• D. Chomsky's Theory of Innate Language Development

Answer: (D)

The main idea here is an inherent blueprint for language structures, captured by the Language Acquisition Device. The LAD is the imagined mental mechanism that contains a prewired universal grammar, providing the template children use to organize the words and rules of their language from the input they receive. This built-in endowment helps explain why language learning tends to unfold in similar ways across diverse languages and why certain patterns appear so early in development. When language development deviates or slows, it can be understood as differences or disruptions in how this internal template is accessed or functioning, rather than something learned entirely from the environment. Transformational Grammar describes how sentences can be transformed from deeper representations to surface forms, not a specific innate blueprint. The Innateness Hypothesis is the broader claim that language ability is inborn, but it does not name the particular mechanism. The label presented as Chomsky's Theory of Innate Language Development likewise refers to innateness in a general sense rather than identifying the exact internal template. The Language Acquisition Device is the precise concept that names that inherent template guiding language structure.
