Key Theories & Frameworks

1. Generative Grammar (Chomsky, 1957)

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.

2. Structuralism (Saussure, 1916)

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.

3. Systemic Functional Linguistics (Halliday, 1961)

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.

4. Cognitive Linguistics (Lakoff & Johnson, 1980; Langacker, 1987)

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.

5. Sociolinguistics (Labov, 1966; Trudgill, 1974)

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."

6. Historical Linguistics (Grimm, 1822; Rask, 1818)

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

Phoneme โ€” The smallest unit of sound that distinguishes meaning. English: /p/ vs. /b/ (pat vs. bat). ~44 phonemes in English. Allophones โ€” variants of a phoneme that don't change meaning.
Morpheme โ€” The smallest unit of meaning. Free morphemes (dog, run) vs. bound morphemes (-s, -ing, un-). Inflectional (grammatical) vs. derivational (changes word class).
Syntax โ€” The rules governing sentence structure. Constituency โ€” phrases and clauses. Grammatical relations โ€” subject, object, verb. Transformations โ€” passive, question, negation.
Semantics โ€” The study of meaning. Lexical semantics โ€” word meaning. Compositional semantics โ€” how word meanings combine. Sense vs. reference. Synonymy, antonymy, hyponymy, polysemy, homonymy.
Pragmatics โ€” The study of meaning in context. Speech acts โ€” promising, requesting, apologizing. Implicature โ€” implied meaning (Grice's Cooperative Principle). Deixis โ€” context-dependent expressions (I, here, now).
Language Acquisition โ€” How children learn language. Critical period hypothesis โ€” language is easiest to learn before puberty. Universal stages โ€” babbling, one-word, two-word, telegraphic. Innate vs. learned โ€” nature vs. nurture.
Language Families

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

Case Study 1: Grimm's Law (1822)

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.

Case Study 2: Labov's New York City Study (1966)

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.

Case Study 3: Nicaraguan Sign Language (1980s)

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.

Case Study 4: The Great Vowel Shift (1350-1700)

Systematic change in English long vowels. Middle English /iห/ โ†’ Modern English /aษช/ (time). /uห/ โ†’ /aสŠ/ (house). /eห/ /iห/ (see). Explains why English spelling doesn't match pronunciation โ€” spelling was fixed before the shift completed.

Practice Questions

Q1: What is the difference between langue and parole?
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.
Q2: What is the difference between phonetics and phonology?
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.
Q3: How does cognitive linguistics differ from generative grammar?
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.
Q4: What is the Sapir-Whorf hypothesis and what are its implications?
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.
Q5: What are the main stages of language acquisition in children?
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.
