Affect vs. Effect: Definitions and Alternatives
Sometimes, even the most experienced writers can mix up words. Understanding their meaning and exploring alternatives can help.
Affect is a verb and means “to influence.” The top definition of affect in Merriam-Webster is “to produce an effect upon (someone or something).” It’s usually read as neutral. If you want a verb that evokes a negative feeling, try upset or disturb; if you want a positive verb, try inspire or sway. If you want a stronger verb, try alter or transform. The word affect can also function as a noun, though that use is usually limited to psychology.
Effect is a noun and means “the result” or “consequence.” The top definition of effect in Merriam-Webster is “something that inevitably follows an antecedent (such as a cause or agent).” It’s usually read as neutral. If you want a noun that evokes a negative feeling, try repercussion or aftermath; if you want a positive noun, try upshot or outcome. If you want a stronger noun, try consequence. Effect can also be a verb meaning “to bring about a result,” but this usage is less common. You’ll know you need the noun effect if you have an article (an or the) before it.

Using Context to Choose the Right Word
If memory tricks don’t work for you, try using context cues to choose the right word. For example, if you’re writing about changing or influencing someone in the future, an ongoing process, or a work-in-progress, you’re probably referring to activity and the best choice will be affect as a verb. Still not sure? Look for a person or an organization doing some work. You know affect as a verb is the right choice when it describes something that influences a person or scenario.
If you’re writing about something that has already happened, you’re probably referring to the outcome and the best choice will be effect as a noun. Still not sure? Look for an if/then situation or cause-and-effect chain of events. You know effect as a noun is the right choice when you’re discussing possible outcomes. You can use effect with the following words: the, any, an, into, on, take, or (but you can’t use them with affect).
