1. Understanding Prefixes and Suffixes

1.1 What Are Prefixes and Suffixes?

• Prefixes are groups of letters added to the beginning of a word to change its meaning.
  • Example:
    • Un- (undo, unhappy)
    • Re- (replay, rewrite)
• Suffixes are added to the end of a word to form a new word or change its grammatical function.
  • Example:
    • -ly (quickly, happily)
    • -ness (kindness, happiness)

1.2 Types of Prefixes and Suffixes

• Common Prefixes
  • Un- (not)
  • Re- (again)
  • Dis- (opposite)
  • Mis- (wrong)
  • Pre- (before)
• Common Suffixes
  • -ing (present participle, e.g., running)
  • -ed (past tense, e.g., walked)
  • -ful (full of, e.g., beautiful)
  • -able (able to be, e.g., washable)
  • -ly (in a certain way, e.g., kindly)

2. Rules for Using Prefixes and Suffixes

2.1 Rules for Prefixes

• A prefix generally changes the meaning of the root word but does not alter its grammatical category.
  • Example:
    • Legal → Illegal (The meaning changes but it remains an adjective.)
• Some prefixes have multiple meanings depending on context:
  • Re- can mean “again” or “back.”
    • Example: “replay” (play again) vs. “retract” (pull back).

2.2 Rules for Suffixes

• Suffixes change the grammatical function of a word.
  • Example:
    • Kind (adjective) → Kindness (noun)
    • Quick (adjective) → Quickly (adverb)
• When adding suffixes, some words may undergo spelling changes, like dropping the final “e.”
  • Example:
    • Make → Making (drop the “e” before adding -ing).

2.3 Key Points to Remember

• Prefixes typically do not affect the spelling of the root word.
• Suffixes often require changes in spelling, particularly when adding certain suffixes to words ending in “e” or “y.”

3. Practical Applications of Prefixes and Suffixes

3.1 Building New Words with Prefixes

• Prefixes can be used to create antonyms or related terms.
  • Example:
    • Happy → Unhappy
    • Appear → Disappear
• Common uses in everyday language include forming opposites or enhancing meanings.
  • Example:
    • Possible → Impossible
    • Approved → Reapproved

3.2 Building New Words with Suffixes

• Suffixes are used to change the form of a word (noun, adjective, verb, adverb).
  • Example:
    • Beauty (noun) → Beautiful (adjective)
    • Happiness (noun) → Happy (adjective)
• Forming adverbs from adjectives:
  • Quick → Quickly
  • Easy → Easily
