WATCH: How To Use "Affect" vs. "Effect"

Affect or effect?

Both of these words are verbs and nouns and their meanings overlap. Very confusing! This slippery duo can send even experienced writers into a spiral of uncertainty. Especially, since many people pronounce them in almost the exact same way.

Here’s a basic guideline for affect vs. effect: Generally, we use affect as a verb (an action word) and effect as a noun (an object word).

What does?affect?mean?

The verb affect means “to act on; produce an effect or change in” as in The cold weather affected the crops?(it produced a change in the crops … probably killing them).

It can also mean “to impress the mind or move the feelings of,” as in The music deeply affected him (the music changed his feelings or thoughts). So, when you’re looking to use one of these two terms to express an action, chances are you’re looking for affect.

If you can substitute affect with another verb, you’ll know you’re using the right word, as in The cold weather damaged the crop, or The music deeply moved him.

What does effect?mean?

Effect is most commonly used as a noun, meaning “result” or “consequence.” So, when you’re writing, try to swap out?effect?for?result and see if it makes sense. For example, His sunburn was an effect of exposure to the sun. His sunburn was a result of exposure to the sun. Effect might also catch you off guard because it appears in two common idioms: in effect, and take effect.

How can you remember the difference?

There’s one trick to help you use the right word in almost every case: the word raven.

What caused all the confusion?

Want to go deep? Much of the confusion surrounding this pair is due to a shared linguistic ancestor. Both words have roots in the Latin verb?facere?meaning “to do, make.”?Affect?derives from the Latin verb?afficere?meaning “to do something to, to have influence on.”?Effect?descends from the Latin verb?efficere, “to make, carry out.”

Sticking to the basic guideline of?effect?as a noun and?affect?as a verb will generally keep you in the clear.

What about the exceptions?

Less frequently, affect can be used as a noun to describe emotion in a psychological context. Example: A sad affect may be a symptom of depression. Affectionate?is a related term with the same root word as affect. Effect can also be a verb meaning “make happen,” but that use is less common. Example: She effected her test score by studying hard. The phrase effect change relies on this verb. Here’s hoping this article effects change in all our vocabularies!
