Morphology

Morphology

  • Definition: Study of the structure of words.

  • Key Concepts:

    • Morphological processes involve the formation and breakdown of words.

    • Words have meaningful subparts known as morphemes.

Key Terminology

  • Noun: Denotes a person, place, or thing.

  • Verb: Represents an action.

  • Adjective: Describes a noun.

  • Adverb: Describes a verb.

  • Preposition: Indicates relationships between words.

  • Determiner: Specifies a noun.

  • Conjunction: Connects words or phrases.

Open and Closed Class Items in the Lexicon

  • Open Class Items: Include nouns, verbs, adjectives, and adverbs.

    • Carry the main semantic content and are content words.

  • Closed Class Items: Include pronouns, prepositions, articles, conjunctions, and function morphemes.

    • Inflectional and derivational affixes also fall under closed class.

Differential Impairment in Aphasics

  • Individuals with language issues often show greater impairment in either open or closed class lexical items, indicating different processing methods in the brain.

Morphemes: Structure of Words

  • Morphology involves breaking down words into morphemes.

  • Example: "friend" can evolve into forms like "friendly," "unfriendly," and more by modifying the base.

Recurring Sequences in Morphology

  • Meaningful sequences like ‘phon’ in communication-related words: phone, phonetic, phonology, etc.

  • Patterns in English: common suffixes and prefixes dictate groupings like past tense (-ed) or negation (un-).

Categories of Morphemes

  • Roots: Core meaning of a word.

  • Affixes: Modify the root meaning/function; can be derivational or inflectional.

Derivational vs. Inflectional Affixes

  • Derivational Affixes: Change the meaning or part of speech (e.g., "un-" reverses the meaning of "happy").

  • Inflectional Affixes: Indicate grammatical relations without altering the fundamental part of speech (e.g., verb tense).

Inflectional Affix Examples

  • 3rd person singular present: -s (She waits).

  • Past tense: -ed (She waited).

  • Plural: -s (The chairs).

Language Inflection Types

  • Inflections can express grammatical aspects such as gender, number, case, and tense. Examples included.

Case Inflections in Nouns

  • Case indicates the role of nouns in sentences: subject or object.

  • Historical examples from Latin and Old English illustrate shifts in grammatical markings.

Modern English Case Markings

  • Pronouns retain case marking, highlighting subject (she), object (her), and genitive ('s).

Morphological Properties Across Languages

  • Variations in inflections across English and French.

  • Some languages achieve grammatical expression differently using function words or strict word order.

Key Points About Inflections

  • Inflections do not change meanings but indicate functions (inflectional morphology generally sits outside derivational affixes).

  • Inflections are crucial for grammatical sentence structure.

Morphemes: Minimal Units of Meaning

  • Can be monomorphemic (single) or polymorphemic (multiple). Examples include explanations of how they differ.

Facts About Morphemes

  1. Morphemes are the smallest units of meaning.

  2. May consist of single segments like ‘s’ for plural or be complex.

  3. The relationship between morphemes and syllables varies.

Allomorphs

  • Definition: Alternative pronunciations of a single morpheme and examples provided (e.g., plural morpheme.)

Bound vs Free Morphemes

  • Free Morphemes: Stand alone (e.g., dog).

  • Bound Morphemes: Must attach to others to have meaning (e.g., -ed).

Morphological Processes

  • Different ways of forming words: affixing, compounding, reduplication, and others.

  • Affix types include prefixes and suffixes, with examples.

Compounding in English

  • Combining two or more free morphemes (e.g., ‘hotdog’).

  • Conditions affecting meaning and stress patterns.

Other Morphological Processes

  • Various methods beyond affixing: reduplication and internal change.

Languages by Morphological Type

  • Analytic (Isolating) Languages: Use individual free morphemes to convey meaning (e.g., Chinese).

  • Synthetic Languages: Use bound morphemes (affixes) attached to roots/stems to convey meaning. These include:

    • Agglutinating Languages: Morphemes are loosely connected with clear boundaries (e.g., Swahili).

    • Fusional Languages: Morphemes are combined, boundaries are not clear, and morphemes may change form (e.g., Spanish, Russian).

    • Polysynthetic Languages: Combine multiple morphemes into complex words, often including several roots and affixes (e.g., Sora).

Hierarchical Structure of Word Formation

  • Word Trees: Visual representations of the structure of words, showing how roots and affixes combine.

  • Examples:

    • "reactivate": re- (prefix) + act (root) + -iv (suffix) + -ate (suffix).

    • "lawful": law (root) + -ful (suffix).

    • "unlawful": un- (prefix) + lawful (base).

Principles of Morphological Analysis

  • Steps for Analysis:

    1. Isolate and compare forms.

    2. Determine if a phonetic form has distinct meanings (distinct morphemes).

    3. Identify if different phonetic forms represent the same morpheme (allomorphs).

Examples and Exercises

  • Tree Diagrams: Draw tree diagrams for words like "blackened," "unacceptable," "reusable," and "dehumidifier" to understand their morphological structure.

  • Morphological Analysis: Analyze words to identify roots and affixes, and understand their functions and meanings.
