Affect and effect are two words that are very easy to confuse. While they may sound alike and have related meanings, they actually have very different grammatical usages. In this article, we’ll provide an overview of affect vs effect, with examples, so that you know when to use each word!
Affect vs effect
The short answer to ‘What’s the difference between affect and effect’, is that “affect” is usually a verb and means to impact or change. While “effect” is typically used as a noun and refers to the result or outcome of a change. However, there are exceptions to this that you need to be aware of. We’ll cover these later on!
Understanding the difference between “affect” and “effect” is essential for clear and effective communication, as using the wrong word can drastically change the intended meaning of a sentence.
To keep things simple, think of it this way; affect is a verb and effect is a noun.
So, if person A affects person B, person B experiences the effect of person A’s actions.
For example, if James pulls Rob out of the way of an oncoming bus, James affects where Rob is standing. The effect on Rob is that he is not hit by the bus and can continue to live a healthy life.
James performed an action by pulling Rob out of the way, which indicates the use of a verb. We therefore use “affect”. The result, or effect, is that Rob is not hit by the bus.
Remember that “effect” is a noun. It refers to the result, consequence, or outcome of a particular action, event, or decision. In this example, the outcome of Rob being pulled out of the way by James was that he was not hit by the bus.
Note: Nouns refer to people, places, things, or ideas, and “effect” is a thing that can be perceived, quantified, and described. Therefore, “effect” is a noun in English grammar.
Let’s take a look at some more examples of when to use affect and effect.
When to use affect
As a verb, “affect” means to produce a change or influence something or someone. It is often used to describe how one thing impacts or alters another thing. For example, “the heat affected the ice cream and caused it to melt.”
However, “affect” is not just used for a physical change, it could also be used in a behavioral or emotional way.
Health or physical impact: “The medication is known to affect heart rate” or “The disease can affect multiple organs.”
Changes in behavior or actions: “The new policy will affect the way we work” or “The bad weather affected our travel plans.”
Emotional or psychological impact: “The sad news affected her deeply” or “The film left a deep impression that affected his mood for days.”
Examples of affect in sentences (as a verb)
- The loss of her job affected her deeply, causing her to feel anxious and depressed.
- The new tax laws will affect small businesses in a significant way.
- Climate change is affecting crop yields, causing farmers to lose profits.
- The teacher’s positive feedback affected the student’s self-esteem and motivation to learn.
- The medication may affect your ability to drive, so it’s important to avoid operating heavy machinery.
- The noise pollution from the nearby construction site is affecting the quality of life for the residents in the area.
- The social media campaign had a profound effect on public opinion, affecting the outcome of the election.
- The pollution in the river is affecting the health of the fish population, leading to a decline in their numbers.
Exception: Affect as a noun
On the topic of emotions, it is worth noting that “affect” can also be used in noun form in psychology to describe a person’s emotional state based upon the way they externally display their emotion or mood, such as with a smile, frown, or blank stare.
For example, “The patient’s flat affect was concerning to the psychiatrist, as it may indicate a serious underlying condition.”
In this case, “affect” refers to emotional expression rather than an action.
If you really want to get technical we can even use “affect” as a verb and a noun in the same sentence! For example, “It’s natural that emotions affect someone’s mood, but Dave’s persistent flat affect is a concern.”
When to use effect
“Effect” is a noun. It refers to the result, consequence, or outcome of a particular action, event, or decision. For example, “The new policy had a positive effect on the company’s profits” or “The medication had some side effects.”
Here are some other examples of when to use effect:
Results of an action: “The effect of the new policy was a decrease in absenteeism among employees.”
Consequences of a situation: “The effect of the pandemic on the economy was a significant decrease in consumer spending.”
Outcomes of an action/decision: “The effect of his resignation was a major shakeup in the company’s leadership.”
Impact of an event: “The hurricane had a devastating effect on the coastal communities, causing widespread damage and displacement.”
Changes in appearance or behavior: “The medication had a noticeable effect on his symptoms, improving his mood and energy levels.”
In general, “effect” is used to describe the result or outcome of something, whether that be an action, situation, event, or decision. It is often used in the context of describing what happens as a direct or indirect consequence of something.
Examples of effect in sentences (as a noun)
- The effect of the new diet and exercise regimen was a noticeable increase in energy and weight loss.

- The domino effect of the market crash led to a global recession and economic downturn.
- The placebo effect is a phenomenon where a fake treatment can have a positive effect on a person’s symptoms due to the power of suggestion.
Exception: Effect as a Verb
While “effect” is primarily used as a noun, it can also be used as a verb in certain contexts. When used as a verb, “effect” means to bring about, cause, or produce something. Just when you thought it couldn’t get any more complicated!
Don’t worry too much though, as this usage of effect is more common in formal or technical writing than in everyday speech.
Examples of effect used as a verb:
“The new management team hopes to effect change in the company’s culture.” In this sentence, “effect” means to bring about or cause change.
“The marketing campaign was designed to effect a shift in consumer behavior.” Here, “effect” means to produce or bring about a specific outcome.
“The government’s policies have failed to effect any significant reduction in crime rates.” In this sentence, “effect” means to achieve or bring about a desired result.
If you were to use “affect” in place of “effect” in any of these sentences it would mean to have an “affect” on the change itself, rather than bringing about or creating a lasting change. In this context “effect” has a more powerful impact when compared to “affect”.
Personal effects is an idiom that refers to the items or possessions that belong to a person and are often carried with them or kept close at hand. Personal effects can include items such as clothing, jewelry, electronics, documents, books, and sentimental objects like photographs or keepsakes.
The term “personal effects” is commonly used in the context of traveling, where it refers to the luggage or belongings that a person takes with them on a trip.
Cause and effect
Cause and effect is a relationship between events or actions where one event, the cause, leads to another event, the effect. In this case, effect refers to the result, consequence, or outcome of what happened as a result of the cause.
