Grammar Bomb: Affect VS Effect

Studying affects test results; the effect is usually better grades.



Affect [THINK: Action word (A)]
Effect [THINK: End-result (E)]


“The verb affect means “to act on; produce an effect or change in.” …It can also mean “to impress the mind or move the feelings of…”

Effect is most commonly used as a noun meaning “result” or “consequence…” …It can be used as a verb to mean “make happen,” but that use is less common.”

“What Is the Difference Between Affect and Effect?

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 Use Effect?

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.””

Affect an Effect…What?

[found on]
“The misuse of the words “affect” and “effect” is such an epidemic that some folks are considering assembling regional support groups to deal with the problem. But while the words are often used incorrectly, deciding whether to use affect or effect isn’t as tough to as you may think.
Let me explain.
Affect is generally used as a verb: A affects B. 
The eye-patch affected my vision. 
In this sentence, the eye-patch (A) influenced my vision (B).
Effect, on the other hand, is almost exclusively used as a noun: (A) had an effect on (B). 
Acting like a pirate has had a negative effect on my social life.
So the basic rule of thumb is that affect is almost always a verb and effect is usually a noun.
There are deviations from this, but when in doubt, stick to the rule.
If you need help remembering, think of this mnemonic device: The action is affect, the end result is effect.
