Difference Between Affect And Effect
Difference Between Affect And Effect
There is often confusion over the words effect and affect. In order to understand which to use, you must know the difference between a noun and a verb.
Effect is a noun. Affect is a verb. If you’re not confident with spotting nouns and verbs, there are workarounds to help.
Examples:
- What effect did foot-and-mouth disease have on your business
(The word
effect
- is a noun.)
Tip: Try substituting the noun effect with the noun consequence to confirm it’s a noun.
Substitution Test: “What consequence did foot-and-mouth disease have on your business?”
(As this sounds okay, effect must be correct.)
- Did foot-and-mouth disease affect your business?
(The word
affect
- is a verb)
Â
Tip: Try substituting the verb affect with the verb transform to confirm it’s a verb.
Substitution Test: “Did foot-and-mouth disease transform your business?”
(As this sounds okay, affect must be correct.)
- Do not allow this incident to effect your decision.
Tip: Do the substitution test.
Substitution Test: “Do not allow this incident to consequence your decision.”
(As this is nonsense, effect must be wrong.)
The Other Substitution Test: “Do not allow this incident to transform your decision.”
(As this sounds okay, affect must be correct.)
- That spiral effect is effecting my eyes.
Note: Sometimes, the noun-substitution test won’t work with consequence because effect is quite a versatile word. You might have to try other nouns, e.g., appearance. If you find yourself trying to use this word as a verb (e.g., appear, appears), then you should be using affect not effect.
HOT TIP
A LITTLE TRICK TO SPOT EFFECTÂ
The word effect has several meanings. It can mean outcome, consequence, or appearance. Try using one of these instead of effect. If the sentence still makes sense, then effect is almost certainly correct.
(This trick works because effect is a noun, just like the words outcome, consequence, and appearance.)
A LITTLE TRICK TO SPOT AFFECT
Try using the verb to transform(in its various forms, e.g., transforming, transformed, transforms) instead of affect. If the sentence still makes sense, then affect is almost certainly correct. However, if you find yourself trying to use transformation, then you should be using effect because both are nouns.
(This trick works because to transform is a verb, just like to affect. )
NO CONFUSION WITH AFFECTING AND AFFECTED
There should be no confusion with affecting or affected. These are always verbs.
BE AWARE
There is a verb to effect. It is quite rare, but it is useful in business writing. It means to bring into being.
- The new policy will be effected as soon as the paper is signed.
