Morpheme Analysis and Types

Morpheme

• Definition: The smallest unit of meaning in a language.

Free Morphemes

• Can stand alone as words.
• Examples:
  • "book"
  • "run"
  • "happy"
• Types:
  • Content morphemes: Carry meaning (nouns, verbs, adjectives).
  • Function morphemes: Serve grammatical purposes (prepositions, conjunctions).

Bound Morphemes

• Cannot stand alone; must attach to a free morpheme.
• Examples:
  • Prefixes: "un-", "re-"
  • Suffixes: "-ing", "-ed", "-s"
• Types:
  • Derivational morphemes: Change the meaning/part of speech (e.g., "happy" to "unhappy").
  • Inflectional morphemes: Modify a word to express different grammatical categories (e.g., tense, number).

Morphological Analysis

• Process of breaking down words into their morphemic components.
• Techniques include:
  • Segmenting words to identify morphemes.
  • Analyzing patterns of morpheme combination.
• Benefits: Understanding language structure, meaning, and variation.

Morpheme Acquisition

• Refers to how language learners (especially children) acquire morphemes.
• Stages:
  • Early acquisition focuses on free morphemes.
  • Gradual incorporation of bound morphemes.
• Influenced by:
  • Frequency and exposure in speech.
  • Cognitive development milestones.

Inflection Vs Derivation

• Inflection:

  • Modifies a word to express grammatical features (e.g., tense, mood, aspect).
  • Does not change the word's part of speech.
  • Example: "cat" (singular) → "cats" (plural).

• Derivation:

  • Creates new words by adding morphemes.
  • Often changes the meaning or the part of speech.
  • Example: "inform" (verb) → "information" (noun).

These notes summarize key concepts surrounding morphemes, their types, analysis, acquisition, and the distinction between inflection and derivation.

• Inflection:
  • Modifies a word to express grammatical features (tense, mood, aspect)
  • Does not change the word's part of speech
  • Example: "cat" (singular) → "cats" (plural)
• Derivation:
  • Creates new words by adding morphemes
