Definition

An effect is a change or result caused by something.

An effect is the result or change that happens because of an action, event, or situation. It answers the question “What happened because of this?” In everyday English, it is often used with cause-and-effect relationships. In formal writing, it commonly appears in phrases like “have an effect on.”

Examples

  • The new rules had a positive effect on safety.
  • Lack of sleep can have a strong effect on your mood.
  • The medicine had no effect on his pain.
  • She lowered her voice for effect.
  • High prices often have an effect on demand.

Common mistake

Learners often confuse effect (a result, usually a noun) with affect (to influence, usually a verb).
