Words that sound similar and look similar are kind of like twins. At first glance, they seem like duplicates, but in the end, a lot of people will be annoyed if you confuse them. Time to stop insulting words, people! Are you using “affect” and “effect” correctly?
In most situations, “affect” is a verb with “influence” being a close synonym. For example, “Quick communications online have affected people’s writing habits.”
In most situations, “effect” is a noun with “result” being a close synonym. For example, “One effect of quick communications online is a proliferation of casual, incorrect writing.”
When you affect something, there is an effect.
However, the English language is never that simple—if you even call this description simple. Affect and effect also have other forms, which add confusion. Nine times out of ten, though, follow the above guide, and you’ll be all set.
Oh, and here’s where the inquisitive read on. More power to you, grammar-curious friends!
“Affect” can also be a verb meaning “to make a display of” or “to deliberately cultivate.” In addition, “affect” can be a noun (egads!) used by psychiatrists and other social scientists referring to “emotion,” but unless you fall into one of those disciplines who are familiar with this use, I wouldn’t recommend using this form.
“Effect” has its own complications. It can be noun of different meanings when discussing your “personal effects” or “sound effects.” “Effect” can also be defined as a verb meaning “to create,” such as in the sentence, “Grammarians of the world effect change for the better.”
Oh, and now I have you staring at word-twins again trying to figure out the difference. Remember the simple definitions first (affect (verb)=influence; effect (noun)=result). Subtleties can come later for the brave and/or scientifically minded.
Happy writing!
