Definition:
Generative linguistics is the research program in formal syntax, initiated by Noam Chomsky in the 1950s, which hypothesizes that the human capacity for language is grounded in an innate, species-specific biological endowment — Universal Grammar (UG) — and aims to characterize, with formal precision, the abstract principles and rules that generate the infinite set of grammatical sentences of any human language from finite means. The generative program has proceeded through several successive theoretical frameworks: Transformational Generative Grammar (1957–), Principles and Parameters theory (Government-Binding Theory, ~1981–), and the Minimalist Program (~1995–). Each successive framework has attempted to move toward simpler, more explanatorily adequate accounts of why human languages have the structural properties they do.
In-Depth Explanation
The Core Commitments
Generative linguistics rests on several foundational commitments:
- Innateness: Children acquire language successfully despite receiving limited, noisy input (the poverty of the stimulus argument). This implies that abstract grammatical knowledge is not fully derivable from experience — it must be part of the child’s biological endowment.
- Universality: All human languages share abstract structural properties (hierarchical phrase structure, displacement/movement, recursion) that reflect the design of Universal Grammar, despite enormous surface variation.
- Formal explicitness: Grammatical knowledge should be characterized as an explicit, formal system — comparable to logical or mathematical notation — not as vague descriptions.
- Internalism (I-language): Linguistics studies the internal linguistic knowledge of an individual speaker (I-language — Internal, Individual, Intensional) rather than an externally defined language community (E-language).
The Transformational Tradition
Chomsky’s Syntactic Structures (1957) and Aspects of the Theory of Syntax (1965) proposed:
- Phrase structure rules: Generate underlying deep structure
- Transformations: Map deep structures to surface structures (e.g., passive transformation, wh-movement)
- Deep structure encodes semantic relationships; surface structure is what is pronounced
Principles and Parameters
Government-Binding (GB) theory (~1981) replaced large sets of language-specific rules with:
- Principles: Universal constraints on all human languages (e.g., subjacency, binding theory)
- Parameters: Binary switches that vary across languages (e.g., the pro-drop parameter: Italian and Spanish allow null subjects; English and French do not)
L1 acquisition in this framework involves parameter-setting from input exposure.
The Minimalist Program
The Minimalist Program (Chomsky 1995–) asks: given that UG exists, why does it have the specific properties it does? The answer pursued is that UG reflects an optimal solution to the demands of the interface conditions — what the phonological system requires and what the semantic system requires. Syntactic operations are reduced to Merge (combining two syntactic objects into one) and Agree (feature checking). Transformations become instances of internal Merge (move) or external Merge (combine).
Relevance for SLA
Generative SLA (the “UG-access” debate) investigates whether adult L2 learners retain access to Universal Grammar:
- Full access: L2 grammar is built from UG principles, constrained by the same principles as L1 grammar
- No access: Adults rely on L1 grammar or general learning mechanisms; UG is not directly available
- Partial access: UG principles are available but parameter-resetting is constrained by the L1 setting
Research evidence is mixed and depends heavily on which UG properties are tested and at what stage of acquisition.
Common Misconceptions
“Generative linguistics claims that all grammars are the same.” Generative linguistics claims that all grammars share abstract structural principles but are parametrically different in specific ways. The goal is to explain both universality and cross-linguistic variation within a single theoretical framework.
