Morpheme Basics and Types Week 2 Part 2 Video 2

Jul 7, 2025

Overview

This lecture covers morphemes, the smallest meaningful units in language, and explains their types, functions, and notation conventions.

Morphemes: Definition and Types

  • A morpheme is the smallest meaningful unit in a language.
  • Morphemes can be roots (like "lime") or affixes (like "-s" for plural).
  • Roots have core meaning and can sometimes stand alone.
  • Affixes modify roots and usually cannot stand alone.
  • Morphemes are sound-meaning combinations that cannot be split further and retain meaning.

Knowing a Morpheme: Three Aspects

  • You must know where a morpheme goes in relation to the root (e.g., before, after, inside).
  • You must know its meaning.
  • You must know its pronunciation.

Free vs. Bound Morphemes

  • Free morphemes can stand alone as words (e.g., "lime").
  • Bound morphemes cannot stand alone and must combine with other morphemes (e.g., "-s", "re-").

Affix Types

  • Prefix: attaches before the root (e.g., "re-" in "rewrite").
  • Suffix: attaches after the root (e.g., "-ness" in "happiness").
  • Infix: inserted within the root (e.g., "-ma-" in "edumacate").
  • Circumfix: surrounds the root with parts before and after (e.g., "ke-...-an" in Malay).

Base vs. Root

  • The base is the form affixes attach to; it may be more complex than a root.
  • All roots can be bases, but not all bases are roots.

Issues with Meaning and Historical Roots

  • Not all sound patterns functioning as roots retain independent meaning in modern language (e.g., "sieve" in "receive," "deceive").
  • For analysis, only treat parts as morphemes if they have a clear, current meaning.

Notating Morphemes with Hyphens

  • No hyphens: free morpheme (e.g., "lime").
  • Hyphen after: prefix (e.g., "re-").
  • Hyphen before: suffix (e.g., "-ness").
  • Hyphens on both sides: infix (e.g., "-ma-").
  • Hyphen placement is crucial for clarity.

Key Terms & Definitions

  • Morpheme — smallest unit of meaning in a language.
  • Root — core morpheme with main meaning; base for affixes.
  • Affix — morpheme attached to a root; includes prefixes, suffixes, infixes, circumfixes.
  • Free Morpheme — can stand alone as a word.
  • Bound Morpheme — cannot stand alone; must combine with others.
  • Prefix — affix before the root.
  • Suffix — affix after the root.
  • Infix — affix inserted inside the root.
  • Circumfix — affix with parts before and after the root.
  • Base — form to which an affix attaches, may be more complex than a root.

Action Items / Next Steps

  • Practice identifying morphemes in words in the upcoming exercise.
  • Pay attention to proper hyphen notation for morphemes.
