11.4 Morphology

Morphology, the study of word structure and formation, is a crucial aspect of linguistics. It examines how words are built from smaller units called morphemes, revealing patterns in language evolution and human communication.

This field explores various processes like inflection, derivation, and compounding. By understanding morphology, we gain insights into how languages adapt, expand vocabularies, and express complex ideas through word structure.

Fundamentals of morphology

• Morphology examines the internal structure of words and how they are formed, providing insights into language patterns and evolution in humanities studies
• Explores the smallest units of meaning in language, shedding light on how humans create and interpret complex linguistic structures

• Examines how morphemes combine to create new words and modify existing ones

Relationship to linguistics

• Forms a core branch of linguistics alongside phonology, syntax, and semantics
• Interfaces with other linguistic subfields, influencing pronunciation, sentence structure, and meaning
• Provides crucial insights into language typology and universal grammar theories
• Contributes to understanding language acquisition and processing in cognitive linguistics

Historical development

• Originated in ancient Indian and Greek grammatical traditions
• Gained prominence in 19th-century comparative linguistics and philology
• Influenced by structuralist approaches in early 20th century (Ferdinand de Saussure)
• Transformed by generative linguistics in mid-20th century (Noam Chomsky)
• Expanded to include cognitive and computational approaches in recent decades

Morphemes and allomorphs

• Morphemes serve as the building blocks of words, allowing for the creation of complex meanings through combinations
• Understanding morphemes and allomorphs reveals patterns in word formation across languages, enriching comparative linguistics studies

Free vs bound morphemes

• Free morphemes stand alone as independent words (cat, run, happy)
• Bound morphemes attach to other morphemes and cannot occur independently
• Prefixes attach to the beginning of words (un-, re-, pre-)
• Suffixes attach to the end of words (-ness, -tion, -ly)
• Infixes insert within words, rare in English but common in other languages

Root words and affixes

• Root words carry the core meaning of a word (read in reading, unreadable)
• Affixes modify or extend the meaning of root words
• Derivational affixes change the word's part of speech or meaning (teach → teacher)
• Inflectional affixes indicate grammatical features without changing meaning (cat → cats)
• Circumfixes surround the root word, common in languages like German (ge-...t in gesagt)

Allomorphic variations

• Allomorphs represent different phonetic realizations of the same morpheme
• Occur due to phonological, grammatical, or lexical conditions
• English plural morpheme has allomorphs /-s/, /-z/, and /-əz/ (cats, dogs, buses)
• Can involve suppletive forms, where the entire word changes (go → went)
• May result from historical sound changes or borrowings from other languages

Word formation processes

• Word formation processes demonstrate the dynamic nature of language, reflecting cultural and societal changes in humanities contexts
• These processes allow languages to adapt and expand their vocabularies to express new concepts and ideas

Inflection vs derivation

• Inflection modifies words to express grammatical categories (tense, number, case)
• Inflectional morphology does not change the word's lexical category (walk → walked)
• Derivation creates new lexemes, often changing the word's part of speech (happy → happiness)
• Derivational morphology can alter the word's meaning significantly (read → readable)
• Languages vary in their reliance on inflection vs derivation for word formation

Compounding and blending

• Compounding combines two or more existing words to form a new word (blackboard, greenhouse)
• Endocentric compounds have a head that determines the word's category (steamboat is a type of boat)
• Exocentric compounds lack a clear head (redhead is not a type of head)
• Blending merges parts of two words to create a new one (smog from smoke + fog)
• Blends often reflect linguistic creativity and neologisms in popular culture (brunch, infomercial)

Conversion and clipping

• Conversion changes a word's part of speech without adding affixes (noun 'email' → verb 'to email')
• Also known as zero derivation or functional shift
• Clipping shortens words while retaining the same meaning (advertisement → ad)
• Back-clipping removes the end of a word (examination → exam)
• Fore-clipping removes the beginning of a word (airplane → plane)

Morphological analysis

• Morphological analysis provides tools for understanding word structure across languages, enhancing cross-cultural linguistic studies
• These analytical techniques reveal underlying patterns in language, contributing to broader theories in cognitive science and anthropology

Identifying morphemes

• Involves breaking down words into their smallest meaningful units
• Requires consideration of both form and meaning
• Utilizes the principle of contrast to distinguish morphemes
• Considers productivity and regularity in morpheme identification
• Accounts for allomorphic variations and suppletion

Segmentation techniques

• Linear segmentation divides words into sequential morphemes (un-believ-able)
• Non-linear segmentation accounts for internal vowel changes (sing → sang)
• Employs the principle of recurrence to identify repeated patterns
• Utilizes minimal pair analysis to isolate morphemes
• Considers morphophonemic alternations in segmentation process

Morphological trees

• Represent hierarchical structure of complex words
• Illustrate relationships between roots, stems, and affixes
• Use branching diagrams to show word formation processes
• Distinguish between inflectional and derivational morphology in tree structure
• Aid in visualizing and analyzing compound words and their components

Cross-linguistic morphology

• Cross-linguistic morphology highlights the diverse ways languages structure words, enriching our understanding of human cognitive diversity
• Studying morphological differences across languages provides insights into cultural and historical factors shaping linguistic evolution

Isolating vs agglutinative languages

• Isolating languages have a low morpheme-per-word ratio (Mandarin Chinese)
• Words in isolating languages tend to consist of single morphemes
• Agglutinative languages combine multiple distinct morphemes (Turkish, Japanese)
• Morphemes in agglutinative languages retain their form and meaning when combined
• Agglutination allows for highly complex word structures with multiple affixes

Fusional languages

• Combine multiple grammatical categories into single morphemes (Latin, Russian)
• Morphemes often undergo significant phonological changes when combined
• Single affixes can express multiple grammatical features simultaneously
• Fusional languages often have complex inflectional systems
• Historical sound changes can lead to increased fusion over time

Polysynthetic languages

• Incorporate many morphemes into a single word, often equivalent to entire sentences
• Common in some Native American languages (Inuktitut, Mohawk)
• Can express complex ideas with highly specific meanings in single words
• Often incorporate noun incorporation, where nouns become part of the verb complex
• Present challenges for traditional word-based linguistic analysis

Morphological typology

• Morphological typology provides a framework for classifying languages, facilitating comparative studies in linguistics and anthropology
• Understanding typological differences enhances our appreciation of linguistic diversity and its relationship to cultural patterns

Word order and morphology

• Interplay between syntactic structure and morphological complexity
• Languages with rigid word order often have less complex morphology (English)
• Free word order languages typically rely more on morphological marking (Latin)
• Case systems in morphology often correlate with flexible word order
• Morphological agreement systems can influence word order flexibility

Head-marking vs dependent-marking

• Head-marking languages mark grammatical relations on the syntactic head (Navajo)
• Dependent-marking languages mark relations on dependents (Turkish)
• Some languages exhibit both head-marking and dependent-marking features (Spanish)
• Marking strategies influence the distribution of morphological complexity in sentences
• Typological distinction provides insights into language processing and acquisition

Morphosyntactic alignment

• Describes how languages treat arguments of intransitive and transitive verbs
• Nominative-accusative alignment treats S and A alike, distinct from O (English)
• Ergative-absolutive alignment treats S and O alike, distinct from A (Basque)
• Split-ergative systems show different alignments based on various factors
• Alignment systems interact with case marking, verb agreement, and word order

Morphology in context

• Examining morphology in context reveals its interconnections with other linguistic domains, enriching our understanding of language as a complex system
• The study of morphological interfaces contributes to interdisciplinary approaches in cognitive science and communication studies

Interface with phonology

• Morphophonemic alternations occur when morphemes affect each other's pronunciation
• Assimilation processes can change the form of morphemes (in-possible → impossible)
• Stress patterns in words can be influenced by morphological structure
• Some languages use tonal changes to mark morphological distinctions
• Phonological rules often apply within morphological domains

Relationship to syntax

• Morphosyntax explores the interaction between word structure and sentence structure
• Agreement systems often involve both morphological and syntactic components
• Clitics occupy an intermediate position between morphology and syntax
• Incorporation processes blur the line between word-level and phrase-level structures
• Syntactic theories must account for morphological complexity in some languages
