When should you use "affect" vs. "effect"? Most of the time "affect" is a verb and "effect" is a noun, but there are exceptions. We have an example, a memory trick, and a cartoon to help you remember when to use "affect" or "effect."
‘Affect’ vs. ‘Effect’: The Exceptions
Affect can be used as a noun when you're talking about psychology--it means the mood that someone appears to have. For example, if you say, "Squiggly displayed a happy affect,” it means Squiggly looks happy, but we don’t really know whether he feels happy. Psychologists find it useful because they know that you can never really understand what someone else is feeling. You can only know how they appear to be feeling.
Notice that I pronounced the word differently. When it’s a noun this way, it’s pronounced [af-ekt].
Effect can be used as a verb that essentially means "to bring about," or "to accomplish,” and you’re most likely to see it in the phrase effect change. For example, you could say, "Aardvark hoped to effect change in the village.”
And in my mind, it’s that German village again. Whole circle fullness! I hope my RAVEN trick helps you remember the difference between affect and effect forever.
