Before we get to the memory trick though, I want to explain the difference between the two words: The majority of the time you
use affect with an a as a verb and effect with an e as a noun.
When Should You Use Affect?
Affect with an a means "to influence," as in, "The arrows affected Aardvark," or "The rain affected Amy's hairdo." Affect can also mean, roughly, "to act in a way that you don't feel," as in,
"She affected an air of superiority."
When Should You UseEffect?
Effect with an e has a lot of subtle meanings as a noun, but to me the meaning "a result" seems to be at the core of all the definitions. For example, you
can say, "The effect was eye-popping," or "The sound effects were amazing," or "The rain had no effect on Amy's hairdo."
Common Uses of Affect and Effect
Most of the time,affect is a verb and effect is a noun.
So, most of the time, affect with an a is a verb and effect with an e is a noun; and now we can get to the mnemonics. First, the mnemonic involves a very easy noun to help you remember: aardvark. Yes, if you can remember aardvark—a very easy noun—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 "avery easy noun" are the same first letters as "affect verb effect noun!" That's avery 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.
So avery easy noun will help you remember that affect with an a is a verb and effect with an e is a noun, and the example will help you see how to use both words in a sentence.
of Affect and Effect
So what about those rare meanings that don't follow the rules I just gave you? Well, affect can be used as a noun when you're talking about psychology--it means
the mood that someone appears to have. For example, "She displayed a happy affect." Psychologists find it useful because they know that you can never really understand what someone else is feeling.
You can only know how they appear to be feeling.
And, effect can be used as a verb that essentially means "to bring about," or "to accomplish." For example, you could say, "Aardvark
hoped to effect change within the burrow."
