Optimality Theory

Optimality Theory (OT) is a constraint-based framework for modeling phonology and syntax, developed by Alan Prince and Paul Smolensky in 1993. The core idea is that languages produce the optimal output that best satisfies a ranked hierarchy of universal constraints. Rather than listing rules, OT explains linguistic phe

N400/P600 Analysis

N400/P600 Analysis is a neurocognitive method using electroencephalography (EEG) to measure event-related potentials (ERPs) that reflect brain responses to linguistic stimuli. The N400 component (a negative deflection at 400 ms) indexes semantic processing and surprise; the P600 component (a positive deflection at 600

Acoustic Phonetics

Acoustic Phonetics is the study of the physical properties of speech sounds using instrumentation to measure and analyze sound waves. Pioneered by Peter Ladefoged and Kenneth Stevens, this method uses spectrograms, formant analysis, and waveform measurements to characterize vowels, consonants, and prosodic features wit

Comparative Method

The Comparative Method is a foundational technique in historical linguistics for reconstructing ancestral languages and establishing genetic relationships between related languages. Pioneered by Sir William Jones in 1786, it systematically compares phonological, morphological, and lexical features across languages to i

Corpus Linguistics

Corpus Linguistics is the study of language based on large, representative collections of texts (corpora) processed by computer. Pioneered by John Sinclair and others, the method uses statistical analysis, concordancing, and computational tools to examine patterns of actual language use. Corpus linguistics has transfor

Dialectometry

Dialectometry is a quantitative method for measuring linguistic distances between dialects or languages using objective metrics applied to phonological, lexical, or phonetic data. Pioneered by Jean Seguy in 1973, dialectometry compares word lists, pronunciations, or phonetic transcriptions across speech varieties to ca

Electropalatography

Electropalatography (EPG) is an instrumental method for measuring tongue-to-palate contact during speech by using a specially designed artificial palate fitted with an array of sensors. Developed by William John Hardcastle in the 1970s, EPG provides detailed real-time visualization of articulation and has applications

Geometric Morphometrics

Geometric morphometrics is a quantitative analytical method that captures, analyzes, and compares the shapes of biological structures (bones, teeth, pottery) using coordinate data from landmarks and outlines. Developed by Fred Bookstein in the 1990s, GMM provides a rigorous statistical framework for studying shape vari

Glottochronology

Glottochronology, or lexicostatistics, is a quantitative method in historical linguistics that estimates the time of divergence between related languages based on the proportion of shared cognates in their basic vocabularies. Developed by Morris Swadesh in 1950, the method assumes that core vocabulary items change at a

HPSG

Head-Driven Phrase Structure Grammar (HPSG) is a constraint-based grammatical framework developed by Carl Pollard and Ivan Sag in 1987. HPSG represents linguistic information (phonological, syntactic, semantic) in typed feature structures and derives well-formed expressions through constraints on these structures. Unli

Internal Reconstruction

Internal Reconstruction is a historical linguistic method that reconstructs earlier stages of a single language by identifying internal inconsistencies, morphological irregularities, and distributional patterns within the language itself. Unlike the Comparative Method, which relies on comparing related languages, Inter

Linguistic Ethnography

Linguistic Ethnography is a qualitative research approach combining ethnographic fieldwork with detailed linguistic analysis to understand language use in cultural context. Developed by researchers like Ben Rampton, it examines how people use language within communities, institutions, and social interactions while payi

Minimalist Program

The Minimalist Program (MP) is a framework for generative syntax developed by Noam Chomsky in 1995, designed to explain linguistic structure while assuming the fewest possible theoretical mechanisms. The program seeks principles that are simple, elegant, and motivated by language evolution. It addresses core questions:

Multimodal Discourse Analysis

Multimodal Discourse Analysis is a method for examining how meaning is created through the integration of multiple modes of communication: language, image, sound, gesture, and spatial arrangement. Developed by Gunther Kress, Theo Van Leeuwen, and others, this approach recognizes that in contemporary communication—from

Prototype Theory

Prototype Theory is a framework for understanding how humans categorize concepts, proposing that categories are organized around prototypes—the most typical or central members. Developed by Eleanor Rosch in 1973, the theory challenges classical logic's view that categories have fixed boundaries defined by necessary-and

Psycholinguistic Eye-Tracking

Psycholinguistic Eye-Tracking is a method that measures eye movements during reading or visual processing to investigate how the mind processes language. Pioneered by Keith Rayner, eye-tracking reveals which parts of text attract attention, how long readers spend on different words, and how eye movements relate to comp

Semantic Feature Analysis

Semantic Feature Analysis, or Componential Analysis, is a method for understanding word meaning by decomposing concepts into minimal meaningful units called semantic features or components. Developed by Ward Goodenough in 1956, this approach represents the meaning of words as bundles of features (e.g., 'woman' = [human

Speech Act Theory

Speech Act Theory is a framework in pragmatics developed by J. L. Austin and refined by John Searle, analyzing language as action. The core insight is that utterances are not merely vehicles for propositions but acts with pragmatic effects: 'I pronounce you married' creates a marriage; 'Please close the door' issues a

Systemic Functional Linguistics

Systemic Functional Linguistics (SFL) is a framework for analyzing language developed by Michael Halliday, viewing language as a system of meaning-making choices where speakers select from available options to express meanings. The approach emphasizes the relationship between language form and social context, analyzing
