language acquisition device
LowAcademic / Technical
Definition
Meaning
A theoretical innate mental faculty that enables humans, particularly children, to naturally acquire language.
A concept in theoretical linguistics and cognitive science, first proposed by Noam Chomsky, suggesting the human brain contains a specialized, biologically-determined system for learning language grammar from limited input.
Linguistics
Semantic Notes
Almost exclusively used in formal linguistics, cognitive science, psycholinguistics, and language teaching theory. It is a proper noun for a specific theoretical construct, often abbreviated as LAD.
Dialectal Variation

Connotations
The term carries the same theoretical weight and potential controversy (debate over its existence) in both varieties.
Frequency
Equally low-frequency and specialised in both UK and US academic contexts.

American English
- The language-acquisition-device hypothesis is central to nativism.

Examples
By CEFR Level
- Linguists talk about a language acquisition device in the brain.
- Chomsky's theory of a language acquisition device suggests that the ability to learn grammar is innate.
- The principal evidence cited for a language acquisition device is the poverty of the stimulus and the uniformity of language acquisition across different cultures.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'device' as физическое устройство (physical device). It is an абстрактный механизм (abstract mechanism) or врождённая способность (innate ability).
- The term is a fixed compound. Do not rearrange the word order (e.g., 'acquisition device of language').
Common Mistakes
- Using it as a general term for any language learning tool (e.g., a textbook or app).
- Confusing it with 'language acquisition support system' (LASS), which refers to social interaction inputs.
- Capitalising all words (only proper when referring specifically to Chomsky's model).

FAQ
Frequently Asked Questions
No, it is a theoretical construct. It refers to the hypothesised innate cognitive faculties for language, not a specific, locatable brain organ.
It was proposed by the American linguist and cognitive scientist Noam Chomsky in the mid-20th century.
The main alternative is the empiricist or usage-based theory, which argues language is learned through general cognitive abilities, social interaction, and exposure, without a specialised innate module.
No, it is a central but controversial concept. It is a cornerstone of the nativist (generativist) school of thought but is rejected by functionalist, cognitive, and usage-based linguists.
