Copy Editor’s Corner | Affect vs. Effect
Let’s start with the two meanings we encounter most often. The following sentences are examples of proper usage:
“A candidate’s debate performance can affect the outcome of an election.”
“Amanda’s exercise routine had a salutary effect on her health.”
But this next sentence is correct, too. It introduces the word effect as a verb, which means “to bring about.”
Jamie wants a president who will effect change, but she doesn’t know what effect each candidate’s proposed policies will have on her life.
(Of course, we don’t recommend using effect twice in the same sentence.)
Finally, affect can be used as a noun, but such usage is rare. Why? Because it is a term used in psychology to describe a person’s mood or emotions. For example, a psychiatrist might describe a patient’s affect as irritable or flat.
Mastering the many meanings of effect and affect will most certainly have a positive effect on your affect.
