## Phonetics & Phonology

### Speech Sounds
Phonetics studies the physical properties of speech sounds; phonology studies how sounds function within particular languages. The IPA provides a universal notation system for transcribing any human speech sound. Every sound is classified by three parameters for cons: place of artic (where airflow is obstructed), manner of artic (how it's obstructed), and voicing (whether vocal folds vibrate).

Place of artic (front to back): bilabial (both lips: /p/, /b/, /m/), labiodental (lower lip + upper teeth: /f/, /v/), dental (tongue + teeth: /θ/ as in "thin", /ð/ as in "this"), alveolar (tongue + alveolar ridge: /t/, /d/, /s/, /z/, /n/, /l/), postalveolar (tongue behind ridge: /ʃ/ as in "ship", /ʒ/ as in "measure"), palatal (tongue + hard palate: /j/ as in "yes"), velar (tongue + soft palate: /k/, /g/, /ŋ/ as in "sing"), glottal (vocal folds: /h/, /ʔ/ as in "uh-oh").

Manner of artic: stops (complete airflow blockage then release: /p/, /t/, /k/), fricatives (narrow channel creates turbulence: /f/, /s/, /ʃ/), affricates (stop + fricative: /tʃ/ as in "church"), nasals (air through nose: /m/, /n/, /ŋ/), approximants (narrow but no turbulence: /l/, /r/, /w/, /j/).

vow are classified by tongue height (high/mid/low), tongue backness (front/central/back), and lip rounding. English has ~11-15 vow phon depending on dialect (far more than the 5 vow letters suggest).

### Phonological Processes
A phon is the smallest unit of sound that distinguishes meaning in a language. /p/ and /b/ are separate phon in English because "pat" and "bat" differ only in that sound (minimal pair test). But /p/ has multiple allophones — in "pat" it's aspirated [pʰ], in "spat" it's unaspirated [p]. English speakers don't notice this difference, but in Hindi or Thai, aspiration distinguishes meaning.

Phonological rules describe systematic patterns: assimilation (sounds become more similar to neighbors — "input" often pronounced [ɪmpʊt], /n/ → /m/ before bilabial /p/), deletion (unstressed syl removal — "chocolate" → [tʃɒklət], "family" → [fæmli]), epenthesis (sound insertion — "something" → [sʌmpθɪŋ], /p/ inserted between /m/ and /θ/), metathesis (sound reordering — "ask" → [æks] in some dialects).

### Prosody
Suprasegmental features operating above the phon level: stress (prominent syl — English distinguishes noun "RECord" from verb "reCORD"), intonation (pitch patterns — rising intonation signals questions in English), tone (pitch distinguishes word meaning — Mandarin "ma" with four tones means mother, hemp, horse, or scold), rhythm (stress-timed like English vs. syllable-timed like Spanish vs. mora-timed like Japanese).

## Morphology

### Morpheme Types
A morph is the smallest meaningful unit. "Unbreakable" has three: un- (pfx, negation) + break (root, core meaning) + -able (sfx, capacity). Free morph stand alone ("break"). Bound morph require attachment (un-, -able).

flx morph encode grammatical information without changing word class: English -s (plural), -ed (past tense), -ing (progressive), -'s (possessive). English has minimal flx compared to languages like Finnish (15 cases), Turkish, or Russian.

deriv morph create new words, often changing word class: -ness (adjective → noun: kind → kindness), -ize (noun → verb: modern → modernize), -ful (noun → adjective: hope → hopeful), un- (adjective → adjective: happy → unhappy, reversing meaning).

### Morphological Typology
Languages fall on a spectrum:

**Isolating/analytic** (few morph per word): Mandarin, Vietnamese. "I" + "past" + "go" + "school" = four separate words, each one morph. Grammatical relationships expressed through word order and separate particles.

**Agglutinative** (many morph per word, clearly segmentable): Turkish, Finnish, Swahili. Turkish "evlerimizden" = ev (house) + ler (plural) + imiz (our) + den (from) = "from our houses." Each morph has one meaning, boundaries are clear.

**Fusional** (morph per word, boundaries blurred): Latin, Russian, Spanish. Spanish "hablamos" = habl- (speak) + -amos (first person + plural + present tense — three meanings fused into one sfx). Individual morph carry multiple grammatical meanings simultaneously.

**Polysynthetic** (entire sentences in one word): Mohawk, Yupik. A single word can incorporate subject, object, verb, and modifiers. Yupik "tuntussuqatarniksaitengqiggtuq" = "He had not yet said again that he was going to hunt reindeer."

## Syntax

### Phrase Structure
Sentences have hierarchical structure, not just linear word sequences. "The old man the boats" is initially misread because we parse "the old man" as a NP, but it's actually "The old [people] man [operate] the boats." Hierarchical structure determines meaning.

Phrase structure rules generate tree structures. Every phrase has a head (the word that determines the phrase's category and properties): NP has a noun head, VP has a verb head, PP has a preposition head. Phrases can nest recursively — a NP can contain a PP which contains another NP: "the cat [PP on [NP the mat [PP in [NP the room]]]]".

### Word Order Typology
Languages cluster into dominant word orders: SOV (Subject-Object-Verb) is most common globally (Japanese, Korean, Turkish, Hindi — ~45% of languages). SVO (English, Mandarin, Spanish — ~42%). VSO (Irish, Arabic, Hawaiian — ~9%). Other orders are rare.

Word order correlates with other properties (Greenberg's universals): SOV languages tend to be postpositional ("the house in" rather than "in the house"), use relative clauses before nouns, and place adjectives before nouns. SVO languages tend to be prepositional with relative clauses and adjectives in varying positions.

### Chomsky's UG & Generative Grammar
Chomsky proposed that humans have innate linguistic knowledge — UG — that constrains possible human languages. Evidence: children acquire language with remarkable speed and uniformity despite variable input (poverty of the stimulus argument), all languages share deep str properties (recursion, hierarchical structure, movement operations).

X-bar theory: all phrases share the same abstract structure: Specifier + Head + Complement. The head selects its complement (a verb "devour" requires an object; "sleep" doesn't). This uniform phrase structure across categories (NP, VP, PP, CP) is claimed to reflect UG.

Movement: Elements can displace from their base position. "What did you eat?" — "what" originates as the object of "eat" (you ate what) but moves to sentence-initial position for question formation. The movement leaves an invisible trace, and the moved element must be interpretable in both positions.

## Semantics & Pragmatics

### Meaning Types
Lex sem: word meanings and relationships. Synonymy (couch/sofa), antonymy (hot/cold — gradable; alive/dead — complementary), hyponymy (rose is a hyponym of flower; flower is a hypernym of rose), meronymy (wheel is a meronym/part of car).

Compositional sem: sentence meaning built from word meanings + structure. "Dog bites man" ≠ "Man bites dog" — same words, different structure, different meaning. Principle of compositionality (Frege): the meaning of a complex expression is determined by the meanings of its parts and the way they are combined.

### Pragmatics: Meaning in Context
Grice's Cooperative Principle: speakers in conversation cooperate by following four maxims:
- **Quantity**: Say enough but not too much
- **Quality**: Say what you believe to be true
- **Relation**: Be relevant
- **Manner**: Be clear and orderly

Implicatures arise from deliberately flouting maxims. "How's the new restaurant?" "Well, the tablecloths were nice." — Violates quantity (says too little) to implicate that the food was bad without stating it directly. The listener infers the unstated meaning.

Speech acts (Austin/Searle): Utterances do things beyond conveying information. "I now pronounce you married" (performative — the words CREATE reality), "Could you pass the salt?" (indirect speech act — grammatically a question, functionally a request), "Nice weather we're having" during a storm (irony — saying the opposite of what's meant).

### Deixis
Expressions whose meaning depends on context: "I" (speaker), "you" (hearer), "here" (speaker's location), "now" (time of utterance), "this/that" (proximity to speaker). These words have no fixed reference — "I" refers to whoever is speaking. Spatial deixis, temporal deixis, and person deixis are universal to all languages.

## Sociolinguistics

### Language Variation
No speaker uses language the same way in all situations. Register variation: formal (academic paper), consultative (doctor-patient), casual (friends), intimate (family). Code-switching: bilingual speakers alternate languages within a conversation, governed by social rules — not random or evidence of confusion.

Dialects are NOT degraded versions of a "standard" — every dialect is a complete, rule-governed system. "Standard" languages are dialects that gained prestige through political, econ, or cultural power. The linguistic maxim: "A language is a dialect with an army and a navy" (Weinreich).

Sociolects correlate with social class, age, ethnicity, gender. Labov's department store study (1966): pronunciation of post-vocalic /r/ in New York correlated with store prestige (Saks > Macy's > S. Klein). When asked to repeat, speakers at all stores increased /r/ pronunciation — demonstrating awareness of prestige norms.

### Language Change
All living languages change constantly. Sound change is regular (Grimm's Law: PIE */p/ → Germanic /f/, explaining Latin "pater" → English "father"). Grammaticalization: lex items become grammatical markers — "going to" (motion verb) → "gonna" (future tense marker). Semantic shift: "nice" meant "foolish" in Middle English, "deer" meant "animal" (any animal), "meat" meant "food" (any food).

### SLA
L1 transfer: L2 learners apply L1 patterns to the new language — source of systematic errors, not random mistakes. Critical period hypothesis: native-like proficiency in phon becomes increasingly difficult after puberty. Grammar acquisition is less age-sensitive. Input, interaction, and motivation are the strongest predictors of L2 success.

Interlanguage: the L2 learner's systematic, evolving grammar — not simply broken L2 but a legitimate system with its own rules that gradually approximates L2 norms. Fossilization occurs when interlanguage stabilizes before reaching target norms, particularly in pronunciation.
