A client emailed me today and pointed out a typo on my part. I had used the word effect where she figured that affect was correct. Unfortunately, it wasn’t a typo — I was just plain wrong. Not in my grammar, but in my choice to use a more obscure form of the word effect when I could have worded the sentence such that affect would have worked just fine.
I used to think of effect as a noun and affect as a verb. Oh, those were the days. When I learned that isn’t quite true, that’s when things got hard again. But it took me years to get comfortable with the spelling of the word “calendar,” so it’s alright that I should have to work on this a little while longer. Following is an explanation of the finer distinctions of affect and effect.
Affect is usually a verb but is occasionally a noun. When it is a verb, it means either “to have an influence on” or, more rarely, “to put on airs” (acting in a way you don’t feel). Two verb examples:
- Green house gas emissions affect the global temperature.
- Even though he was seething, he affected a pleasant demeanor.
The only time affect is a noun is when it is used to describe someone’s mood, sometimes in a psychological context. For instance, “He had a chilling affect from the start.” This ties into the second verb use of affect because someone’s exterior demeanor is not necessarily reflective of how they are feeling inside.
On to effect, which is usually a noun, but occasionally a verb. It’s exact meaning is subtle, but has to do with the result the subject of a sentence has. And sometimes it just means “stuff.” Examples of effect as a noun:
- My criticism had a negative effect on him.
- The sound effects were incredible.
- Take your personal effects into the green room.
Now, when effect is a verb, it is used in a way to mean “to create.” This is distinguishable from affect, which usually means “to have an influence on.” Here is how effect may be accurately used as a verb:
- She hopes her blog post will effect a change in the use of affect and effect.
- This new policy will effect how people choose insurance.
And, here, I’m not sure whether its a verb, a noun, or something else but make a note:
- When the changes take effect, you’ll have to re-register.
I hope this little explanation has had a positive effect on your understanding of the differences between effect and affect.
