Lexicology Course
Master the science of words from their internal structure and historical origins to their social variation and computational analysis. This course gives you a rigorous, research-grounded understanding of how vocabulary works across languages, contexts, and communities. Whether you're pursuing linguistics, language teaching, or lexicography, you'll build expertise that translates directly into professional practice.
What you will learn:
In this course you will gain a solid grasp of lexicology, covering word formation, lexical semantics, historical etymology, and socio‑lexical variation. You will learn to analyse word structure with morphological frameworks and apply semantic theories to explain how meaning is encoded and interpreted. The curriculum introduces corpus‑linguistics tools for quantitative investigation of lexical patterns. You will also explore cognitive and computational approaches to the lexicon, such as distributional semantics and psycholinguistic models. Applied modules link theory to vocabulary teaching, dictionary design, and lexical consulting. By course end you will possess analytical skills and a methodological toolkit to conduct original lexicological research and present findings to specialist and general audiences.

Foundations of Lexicology
Lesson 1 • Defining Lexicology and Its Scope
Lexicology is defined as the study of words, their forms, meanings, and relations. This grounds all subsequent analysis in a shared disciplinary framework.
Lesson 2 • Word Forms and Identification
Criteria for identifying words across spoken and written language are established. Students apply these criteria to distinguish words from morphemes and phrases.
Lesson 3 • The Lexicon as a System
The mental and linguistic lexicon is examined as a structured inventory. Students understand how words form networks rather than isolated entries.
Lesson 4 • Overview of Lexical Research Methods
Core methodologies used in lexicological research are surveyed. Students connect method choice to research questions they will encounter throughout the course.
Chapter 2HideHide detailsSee detailsWord Structure and Morphology
Word Structure and Morphology
Lesson 1 • Morphological Analysis Techniques
Segmentation and identification procedures are practised on authentic word samples. Students develop reliable analytical habits for decomposing complex words.
Lesson 2 • Compounding and Other Word-Formation Processes
Compounding, conversion, blending, clipping, and acronymy are analysed as productive processes. Students classify novel words by the process that generated them.
Lesson 3 • Derivation and Affixation
Prefixes, suffixes, and their semantic and grammatical effects are examined systematically. Students predict meaning and category changes produced by affixation.
Lesson 4 • Morphemes: Types and Functions
Free, bound, derivational, and inflectional morphemes are defined and contrasted. This taxonomy underpins all word-formation analysis in the chapter.
Chapter 3HideHide detailsSee detailsLexical Semantics: Meaning and Sense
Lexical Semantics: Meaning and Sense
Lesson 1 • Theories of Lexical Meaning
Referential, conceptual, and use-based theories of meaning are compared. Students evaluate each theory's explanatory power for lexical phenomena.
Lesson 2 • Sense Relations: Synonymy and Antonymy
Synonymy, antonymy, and their subtypes are defined with diagnostic tests. Students map sense relations within a lexical field accurately.
Lesson 3 • Hyponymy, Meronymy, and Lexical Fields
Hierarchical and part-whole relations structure vocabulary into organised fields. Students construct lexical hierarchies and identify field boundaries.
Lesson 4 • Semantic Features and Components
Componential analysis decomposes word meaning into binary semantic features. Students apply feature matrices to distinguish near-synonyms and related terms.
Lesson 5 • Polysemy and Homonymy
Criteria distinguishing polysemy from homonymy are established and applied. Students resolve ambiguity in lexical entries using etymological and semantic evidence.
Chapter 4HideHide detailsSee detailsWord Meaning in Context
Word Meaning in Context
Lesson 1 • Connotation, Denotation, and Register
Denotative and connotative dimensions of meaning are distinguished with examples. Students assess how register and style shift lexical choice.
Lesson 2 • Metaphor and Metonymy in the Lexicon
Conceptual metaphor and metonymy are shown to motivate systematic lexical patterns. Students trace metaphorical mappings across semantic domains.
Lesson 3 • Collocation and Lexical Restrictions
Collocational patterns reveal constraints on word co-occurrence beyond grammar. Students identify strong and weak collocates using frequency-based evidence.
Lesson 4 • Idioms and Fixed Expressions
Idioms, proverbs, and formulaic sequences are analysed for compositionality and fixedness. Students classify multi-word units on a transparency continuum.
Chapter 5HideHide detailsSee detailsHistorical and Etymological Lexicology
Historical and Etymological Lexicology
Lesson 1 • Sources of Vocabulary: Native and Borrowed
Native heritage words are contrasted with loanwords from major donor languages. Students identify etymological layers and their stylistic implications.
Lesson 2 • Neologisms and Lexical Innovation
Mechanisms driving new word creation in contemporary language are examined. Students analyse neologisms by formation process and social motivation.
Lesson 3 • Etymology and Word History
Etymological research methods and resources are introduced for tracing word origins. Students reconstruct word histories using etymological dictionaries and databases.
Lesson 4 • Processes of Semantic Change
Broadening, narrowing, amelioration, pejoration, and metaphorical shift are defined. Students document semantic change trajectories using historical evidence.
Chapter 6HideHide detailsSee detailsSociolexicology and Lexical Variation
Sociolexicology and Lexical Variation
Lesson 1 • Dialect and Regional Lexical Variation
Regional dialects exhibit distinct vocabulary that reflects geographic and cultural history. Students map lexical isoglosses and interpret dialect atlas data.
Lesson 2 • Gender, Age, and Lexical Choice
Empirical research on gender- and age-related lexical preferences is reviewed critically. Students evaluate methodological challenges in sociolexical studies.
Lesson 3 • Social and Occupational Lexicons
Sociolects, jargon, and professional registers encode group identity and expertise. Students analyse specialised vocabulary for its social and functional roles.
Lesson 4 • World Englishes and Global Lexical Diversity
Lexical features of major world English varieties are compared systematically. Students assess how global spread creates new lexical norms and standards.
Chapter 7HideHide detailsSee detailsCorpus Lexicology and Quantitative Methods
Corpus Lexicology and Quantitative Methods
Lesson 1 • Semantic Prosody and Discourse Patterns
Semantic prosody describes the attitudinal colouring words acquire through habitual co-occurrence. Students identify prosodic patterns and their discourse implications.
Lesson 2 • Introduction to Corpus Linguistics for Lexicology
Corpus design, annotation, and retrieval principles are introduced as tools for lexical research. Students navigate a reference corpus to extract word frequency data.
Lesson 3 • Designing a Corpus Lexical Study
Research design principles are applied to plan a complete corpus-based lexical investigation. Students produce a study protocol with justified methodological choices.
Lesson 4 • Collocation Analysis and Association Measures
Statistical association measures quantify collocational strength between word pairs. Students select appropriate measures and interpret collocate profiles.
Lesson 5 • Frequency, Dispersion, and Keyness
Frequency lists, dispersion measures, and keyness statistics reveal lexical significance. Students compute and interpret these metrics using corpus software.
Chapter 8HideHide detailsSee detailsApplied Lexicology and Vocabulary Pedagogy
Applied Lexicology and Vocabulary Pedagogy
Lesson 1 • Principles of Vocabulary Instruction
Evidence-based principles for teaching vocabulary explicitly and implicitly are examined. Students evaluate instructional techniques against acquisition research.
Lesson 2 • Evaluating and Creating Lexical Resources
Criteria for evaluating word lists, thesauri, and digital lexical tools are established. Students produce a justified lexical resource for a specified learner audience.
Lesson 3 • Terminology and Specialised Vocabulary
Terminological theory and specialised vocabulary management are introduced for professional contexts. Students compile a small terminological glossary from a domain text.
Lesson 4 • Lexicography: Dictionary Types and Design
Dictionary typology, macrostructure, and microstructure are analysed as applied lexicology. Students critique dictionary entries using lexicological criteria.
Lesson 5 • Vocabulary Acquisition and Lexical Development
First- and second-language vocabulary acquisition research informs instructional design. Students connect acquisition findings to pedagogical decisions.
