You should be able to identify the cause and effect within a story. These two elements explain the relationship between two actions. The cause is what occurs to initiate the effect.

Tip

Cause: What triggers an event, circumstance, or situation

Effect: The result of an event, circumstance, or situation

Consider this example:

  • The glass broke because Suzy dropped it.
    • Cause: dropping the glass
    • Effect: the glass breaking

Purpose of Cause and Effect

Understanding cause and effect helps you answer the "why" question. If you read that Sam was very sad, you will wonder why he is sad. If you read that Sam's best friend is moving away, you can answer the question "Why is Sam sad?" Sam's best friend moving is the reason why Sam is sad. His sadness is the effect of Sam's best friend moving.

Identifying Cause and Effect

Prepositions can help you identify the cause of a sentence. Learn to recognize words, such as, "because," "since," "therefore," "so," and "if" to figure out which action is the cause and which action is the effect. Consider these examples:

  • Since Ed had to get up early Tuesday morning, he went to bed early Monday night.
    • Cause: Ed had to get up early Tuesday morning. "Since" suggests the phrase is the cause.
    • Effect: He went to bed early Monday night.
  • Sara was making a cake because it was her mother's birthday.
    • Cause: Sara's mother's birthday. "Because" is a clue the phrase is the cause.
    • Effect: Sara made a cake.
  • Thomas earned fifty dollars last week, so he was able to go to the zoo with Andy.
    • Cause: Earning 50 dollars is the cause. "So" is a clue going to the zoo is the effect.
    • Effect: He went to the zoo.
  • Since Joe's family had a long way to go, they left early.
