The Ultimate Affect vs Effect Trick: RAVEN

If you find yourself stuck and need a quick way to decide which word to use, many educators suggest a popular mnemonic device. This affect vs effect trick is known as RAVEN.

• R = Remember

• V = Verb

• E = Effect is a

• N = Noun

By keeping "RAVEN" in mind, you can instantly verify your choice. If you are describing an action, choose the one that starts with 'A' (Affect).

However, for school-level grammar, sticking to the Verb (Affect) and Noun (Effect) rule will serve you perfectly.
