Phonology: The study and mental organization of speech sounds and sound patterns in language. It describes how speakers organize sound contrasts within a language.
Language acquisition: The process by which people develop the ability to understand and use a language. Children acquire complex linguistic patterns through development and experience.
Noam Chomsky: An American linguist and cognitive scientist known for influential theories of grammar and language acquisition. His account of innate grammatical knowledge reshaped debates about language and learning.
Universal grammar: A proposed system of innate constraints that helps explain the structure of human languages. It is a prominent account of the knowledge underlying language acquisition.
Bilingualism: The ability to use two languages, which may vary by context, proficiency, and skill. It shows how the language capacity supports more than one linguistic system.
Morphology: The study of how words are formed from meaningful units called morphemes. It explains how language builds words from smaller meaningful parts.
Statistical learning: The ability to detect patterns and regularities in sequences through exposure. Learners can use distributional patterns in speech to discover linguistic structure.
Steven Pinker: A Canadian-American cognitive scientist whose work examines language, mind, and human nature. His writing helped popularize the view of language as an evolved human ability.
Usage-based linguistics: An approach that explains linguistic structure through usage, learning, and general cognitive processes. It contrasts with accounts that posit rich, language-specific innate grammatical knowledge.
Literacy: The ability to read and write, including the knowledge and practices needed to use written language. Writing extends language beyond face-to-face speech and enables durable communication.
