# Linguistics

## What linguistics is

The scientific study of language: its structure, use, acquisition, and social variation.
Not prescriptive (what you SHOULD say) — descriptive (what people ACTUALLY say).

## Language structure

### Phonology

Study of sounds in language.
**Phoneme:** Smallest sound unit that distinguishes meaning. "pin" vs "bin" — /p/ and /b/ are phonemes.
**Allophone:** Variant of a phoneme that doesn't change meaning. Aspirated /p/ in "pin" vs. unaspirated in "spin."
**International Phonetic Alphabet (IPA):** Universal notation for speech sounds.
~6,000-7,000 human languages. Enormous diversity in phonological systems.
Mandarin: 4 tones. English: ~44 phonemes. Hawaiian: ~13 phonemes.

### Morphology

Study of word structure.
**Morpheme:** Smallest unit of meaning. "unhappiness" = un + happy + ness (3 morphemes).
**Free morpheme:** Stands alone. "dog," "run."
**Bound morpheme:** Attaches to free morpheme. "-ing," "un-," "-ness."
**Inflection:** Grammatical information (plurality, tense). "walk" → "walks," "walked."
**Derivation:** New words. "teach" → "teacher" → "unteachable."

### Syntax

Study of sentence structure.
**Phrase structure rules:** How words combine into phrases and sentences.
Universal: Subject-Verb-Object is most common order globally (~45% of languages).
But languages vary: SOV (Japanese, Turkish, Latin), VSO (Arabic, Irish), SVO (English, Mandarin, Spanish).

**Recursion:** Language allows infinite sentences from finite elements. Embedded clauses: "The dog that chased the cat that ate the rat..."

### Semantics

Study of meaning.
**Sense vs. reference:** "Morning star" and "evening star" have different senses but same reference (Venus).
**Semantic roles:** Agent (doer), Patient (affected), Theme, Instrument, Experiencer.
**Entailment:** If "The cat died" is true, "The cat was alive" is entailed as formerly true.

### Pragmatics

Meaning in context. How context shapes interpretation.
**Speech acts (Austin, Searle):** Utterances as actions. Asserting, questioning, promising, ordering.
**Grice's maxims:** Conversational cooperation principles.
Quantity: Say enough, not too much.
Quality: Be truthful.
Relation: Be relevant.
Manner: Be clear, brief, orderly.
Flouting maxims creates implicature: "Can you pass the salt?" is not a question about physical ability — it's a request.

## Language acquisition

**Universal stages:** Babbling (6-9 mo) → First words (12 mo) → Two-word stage (18-24 mo) → Telegraphic speech → Full grammar (by ~5).
**Critical period hypothesis:** Language acquisition most natural before puberty. After puberty: can learn languages but never fully native-like for most learners (debate ongoing).
**Statistical learning:** Infants are extraordinary statistical learners — tracking co-occurrence of sounds/words.

## Language variation

**Dialect:** Systematic variation in a language across regions or social groups. Every speaker has a dialect — including "standard" dialects which are just socially prestigious, not linguistically superior.
**Register:** Variation based on social context (formal/informal, technical/non-technical).
**Code-switching:** Moving between languages or dialects. Normal and competent behavior, not a deficit.
