Thirsty Thursday: If you are like me, this trick will help you keep affect and effect sorted in your writings. Simply remember “aardvark is a very easy noun” and you’ll always remember that affect with an a is a verb and effect with an e is a noun. Why? Because the first letters of “a very easy noun” are the same first letters as “affect verb effect noun!” That’s a very easy noun. Affect (with an a) verb effect (with an e) noun.
“But why Aardvark?” you ask. Because there’s also an example to help you remember. It’s “The arrows affected Aardvark. The effect was eye-popping.” It should be easy to remember that affect with an a goes with the a-words, arrow and aardvark, and that effect with an e goes with the e-word, eye-popping. If you can visualize the sentences, “The arrows affected the aardvark. The effect was eye-popping,” it’s pretty easy to see that affect with an a is a verb and effect with an e is a noun.
