Key Theories & Frameworks
Language is an innate, rule-governed system. Universal Grammar โ all languages share a common underlying structure. Deep structure vs. surface structure. Transformational rules generate all grammatical sentences. "Colorless green ideas sleep furiously" โ grammatical but meaningless.
Language is a system of signs. Signifier (sound image) + signified (concept) = sign. Arbitrary relationship between them. Langue (system) vs. parole (individual utterance). Synchronic (at a point in time) vs. diachronic (historical) study.
Language is a social semiotic โ a resource for making meaning. Three metafunctions: ideational (representing experience), interpersonal (enacting relationships), textual (organizing discourse). Language varies by context โ register, genre, field, tenor, mode.
Language reflects conceptual structure. Metaphor is not just linguistic but conceptual โ "argument is war," "time is money." Embodied cognition โ meaning grounded in bodily experience. Prototype theory โ categories have central and peripheral members.
Language varies by social factors โ class, gender, age, ethnicity. Language change happens in communities. Code-switching โ alternating between languages/dialects. Language attitudes โ prestige, stigma, and identity. "The social stratification of English in New York City."
Languages change systematically over time. Sound laws โ regular sound changes (Grimm's Law). Language families โ Indo-European, Sino-Tibetan, Afro-Asiatic. Reconstruction โ proto-languages. Language contact โ borrowing, creoles, pidgins.
Core Concepts
Indo-European (English, Spanish, Hindi, Russian), Sino-Tibetan (Chinese, Tibetan), Afro-Asiatic (Arabic, Hebrew), Niger-Congo (Swahili, Yoruba), Austronesian (Malay, Tagalog), Dravidian (Tamil, Telugu). ~7,000 languages worldwide โ half endangered.
Case Studies & Examples
Jacob Grimm discovered systematic sound shifts in Germanic languages. Proto-Indo-European p โ Germanic f (pater โ father). t โ th (tres โ three). k โ h (centum โ hundred). Demonstrated that sound change is regular โ foundation of historical linguistics.
William Labov studied pronunciation of /r/ in New York department stores. Higher-end stores (Saks) โ more /r/ pronunciation. Lower-end stores (S. Klein) โ less /r/. Demonstrated that language variation correlates with social class โ foundation of sociolinguistics.
Deaf children in Nicaragua, brought together in schools, created a new sign language. Started as home signs โ pidgin โ creole (full language). Demonstrated that language is innate โ children create language when exposed to linguistic community. Unique natural experiment.
Systematic change in English long vowels. Middle English /iห/ โ Modern English /aษช/ (time). /uห/ โ /aส/ (house). /eห/ /iห/ (see). Explains why English spelling doesn't match pronunciation โ spelling was fixed before the shift completed.
Practice Questions
A: Langue: the abstract system of language โ the shared knowledge of a speech community. Parole: individual speech acts โ actual utterances. Saussure: linguistics should study langue (the system), not parole (individual performance). Langue is social; parole is individual.
A: Phonetics: the physical study of speech sounds โ how they are produced (articulatory), transmitted (acoustic), and perceived (auditory). Phonology: the abstract study of sound systems โ how sounds function in a particular language. Phonetics is universal; phonology is language-specific.
A: Generative grammar (Chomsky): language is an autonomous, innate module. Universal Grammar โ all languages share a common structure. Cognitive linguistics (Lakoff, Langacker): language reflects general cognition. Metaphor is conceptual, not just linguistic. Meaning is embodied and experiential. No separate language module.
A: Sapir-Whorf hypothesis: language shapes thought. Strong version (linguistic determinism): language determines thought. Weak version (linguistic relativity): language influences thought. Examples: Hopi time, Inuit snow words, color terms. Most linguists accept weak version, reject strong version.
A: (1) Babbling (6-12 months) โ experimenting with sounds, (2) One-word stage (12-18 months) โ single words, (3) Two-word stage (18-24 months) โ telegraphic speech, (4) Telegraphic stage (2-3 years) โ short sentences without function words, (5) Later multiword (3+ years) โ increasingly complex grammar. Universal stages across languages and cultures.
