Determining Word Meanings

• Identify the Base Word: Start by recognizing the root of the word (e.g., “happy” in “unhappy”).
• Analyze the Prefix/Suffix: Determine the meaning of the prefix or suffix and how it affects the base word (e.g., “un-” means “not,” so “unhappy” means “not happy”).
• Context Clues: Use the context in which the word is used to help understand its meaning.

Examples

• Prefix Example: “Replay” (re- means again, so replay means to play again).
• Suffix Example: “Careless” (-less means without, so careless means without care).
