Affect and Effect are twins. Sometimes you can tell them apart, but other days it’s difficult.
I hope this post will have a lasting effect on you. (See what I did there?)
Affect
Affect is a verb. You use it to influence something. It can be used in the act of changing something.
Examples:
The book affected me to do something inspirational. (The book influenced me to do something.)
His words affected me so much that I would do something I’d regret. (He influenced me to do something.)
Effect
Effect is a noun. You use it when you’re talking about the change itself or the result of something.
Examples:
The drug has many side effects. (Taking the medicine can result in other symptoms.)
The remix of the song had a higher effect as the original version. (Listening to the remix song resulted in better buys.)
I hope this post affected you to make better grammatic choices. (Okay, I’ll stop now.)
