Similar words or homophones can be considered as the most confusing kind of words. Often, people who have a very firm command over English get baffled while using these certain words. And the worst part is that we have to use them regularly in our day-to-day life.

Two of the most common words on the list are “affect” and “effect.” Both these words are easy to mix up. Most of us do not have a clear idea of when and how to use “affect and effect.” So, what is the difference between the two?

Affect vs. effect: Just a basic insight –

It is quite evident to get confused between these two words, as both of them have similar spellings. There is a difference of just a single letter. This makes people get mistaken, and hence many English speakers do not know when to use “affect” and “effect” in a sentence.

When it comes to students, they need to be super careful as when they use these words incorrectly in their assignment; there are chances that the teacher will give gives low marks that can result in mediocre overall grades. And you surely don’t want to be mediocre, right?

If you among those who still mess up the use of “affect” and “effect,” then we have definitely mentioned things that you should know, which can help to solve your problem.

So let’s start with the basics.

Definition of “affect” and “effect” –

affect and effect

To use words appropriately, you must understand their meanings. Otherwise, the confusion between “affect” and “effect” will never be resolved, and you won’t be able to use it in proper places.

  • What do you mean by “Effect” – This word can be considered as the result of an action. With using “effect,” there needs to be a cause so that you can mention its impact. For instance, excessive use of mobile phones can have a damaging effect on your eyes. When you use the term “effect”, it should be applied as a form of a noun. While establishing the impact of any phenomenon, the word effect is used in context.
  • What do you mean by “Affect” – This word resembles the verb form. It means to influence something or to produce a change. This word is usually used to show how something has influenced an action to happen. For instance, Lily was crying besides me, and all of us were affected by the cries.

These are the most simplistic definition of these “affect” and “effect.” Now it is time that you dive into some more complex conditions of using these words. As you write, you may get confused about when to use “affect” and “effect.”

Difference between affect and effect –

Is it affect or effect? The first thing you need to understand is that affect is a verb, whereas “effect” is a noun. At least, this works in most cases as there are some expectations which we will talk about later.

Often, you will find words like these in your parts of speech –

So if X affects Y, Y experiences the effect of A’s action.

Confusing huh?

Imagine that A pushes B into a pond. A affects where B is standing. The fact that B is wet is the effect of A’s irresistible urge to shove him into a pond. Because A performed an action that indicates the utilize of a verb: affect. The result of that verb is “wet,” a noun (effect) that is probably causing B a lot of trouble.

Well, you must understand that affect and effect are different parts of speech, but they sound almost identical. Similar sound pairs are tricky because many people pronounce them as homophones, which means, almost sound the same. Bear/bare and write/right are also some of the most common examples that you get to hear on a regular basis.

So when you are writing the right word, you need to consider a few rules that can help you get through the fight.

Rules of affect and effect – 

Now that you know the definition of both these terms, it is time that you learn about the difference. The main difference between these words is said to be in their usage. “Affect” is a verb, while “effect” is used as a noun. As regards the general rules of English grammar, the position of these words will be different. But there are exceptions here as well, which you’ll learn about later.

When to use “affect”?

“Affect implies to influence or produce a change in something.”

Keeping the exceptions aside, “affect” should is always used as a verb. The significance of this word is to influence or to create a change in something. Here are a few examples that may help you understand how to use this word in a sentence.

Examples of affect –

Examples of affect

(Bright Hub, “Sustainable development to positively affect environments”)

Gravity affects everything in the universe, but the amount of gravity affecting an object depends on two things: the masses of the objects being attracted and the distance between the objects.

(Study.com, “The Effects of Mass Distance on Gravity”)

And we could do nothing to help them; Dunham was crying quietly beside me, and all the men were affected by the piteous cries.

(John Keegan, The First World War)

In the last example, the men are “affected” because they have changed by the disturbing events of the war. However, this change also has an emotional factor; When an individual is affected by an event, that often means that the effect is primarily on the emotional or psychological level—more on that in the exceptions section.

When to use “effect”?

“Effect means the result of a change that can be said to be the result of affect.”

Affect versus effect: How to remember the difference

Are you looking for a way that can help you remember the difference between the terms?

Remember, not to lose sight of the prize.

So, the simplest way to do this, memorize the first letter of each word. “Affect” starts with A for Action, which means it’s a verb, and with “Effect”, you can jump directly from “Cause” to “Effect” on that convenient E.

If you memorize that letter trick, you won’t get it wrong ever. In other words, just remember that you spell them correctly.

Beware of exceptions!

Now that you’ve mastered the basic difference, effect as a noun and affect as a verb, it’s time to change things up. In some contexts, the “effect” is a verb, and the “affect” is a noun. Indeed it is confusing!

Effect as a verb:

There are some cases where the word “effect” is used as a verb in some context. However, it is important to understand that the meaning of the word changes completely. The significance of the term “effect” as a verb implies to produce that is generally utilized in conjunction with words like “change” and/or “solutions.”

Check out this example: The Government effected some crucial changes in the country’s economy.

In this sentence, the word “effect” is used for execution. The sentence actually meant: “The Government executed some change in the country’s economy.

Are you wondering about using “affect” (which is a real verb) in this sentence to have the same meaning? If so, then you are absolutely wrong as “affect” stands for “impact” or “change.” If you use it in the sentence, then the entire scenario would vary with a huge change in the meaning.

“The Government influenced some changes in the country’s economy” is clearly not what the sentence is intended to convey. However, the sentence is not wrong. In a certain context, “affected a change” would also make sense. So if you wonder which of these sentences is correct, the answer is both, but in a different context.

Affect as a noun:

The word “affect” is used in its noun form when it is implied for emotion or feeling. Although the word is used primarily as a verb, you can use the word as a noun in the same way as in the following example:

Tim’s has a certain kind of affection for his best friend.”

Here, it is evident, and you can clearly see that “affect” has been used instead of the word feeling or emotion. If you used effect instead of affect in the sentence, it wouldn’t have made any sense.

Affected as an adjective:

In addition to being used as the past and past particle form of “affect,” the word “affected” can also work as an adjective in various sentences, in different contexts. It usually means pretentious, artificial, designed to impress, and the term is generally not said to praise someone. Rather, it is used to describe something or someone who acts as if they are more important than they really are.

Still, confused? Here is an example of using “affected” as an adjective in a sentence:

“Most of my teammates laughed, affected by our boss’s joke.”

Here, it is evident how and what the word “affected” is used for. We could not have used the word “effected” here as it would entirely change the meaning of the sentence. Therefore, there should be no question about the choice of the ideal word: affected or affected.

Affecting vs. Effecting: Common Mistakes Made –

As mixing over these two words persists, the typical mistake people make is primarily in the use of the words. Most of them exchange the word while using it.

For example,

“The knee surgery had an adverse “effect” on her gait.”

Here, “effect” is an incorrect choice of words because the sentence was meant to indicate that knee surgery had a negative influence on a person’s gait. Here, “affect” would have been the right choice of word. Keep in mind the mistake with the use of affect versus effect can change the whole sentence and entirely change the meaning.

While using the word “effect” in the same sentence, the construction has to be different. Here it is.

“Due to the knee surgery, as an “effect,” her gait became difficult”.

Here, the sentence acknowledges that due to knee surgery, her walking rhythm became problematic. Therefore, it is the result of knee surgery.

Another common mistake they make when trying to use “effect” as a verb in some of the contexts. For instance:

“They effected their escape through the back door.”

Here the word “effected” can be utilized as a verb. But, the difficulty in the choice of the word between affect and effect still remains.

These are the most common mistakes that people make out of confusion. Most of the people who are good in English also face the dilemma of using the right word that justifies the context.

The conclusion (when to use affect or effect) –

Let’s recap how and when to use which word among affect and effect ideally!

Use “affect” as the verb in a sentence when you’re talking about making a difference or making a difference. For example, a new discovery can affect a scientific theory, and failing a test can affect someone’s mood.

Here are some synonyms for affect: alter, change, influence, modify, and impact (the verb version). That list should affect your understanding of the word. In this case, “affect” would mean “improve.”

“Effect” is a noun and is the result of an event or situation that generated a change. The effect of the change can be large or small, but the fact that something has changed is what makes the nominal form of the effect so important. For example, you may feel the effects of a cold or an earthquake, and sunrise can have a positive effect on your mood.

Some synonyms for effect include words such as outcome, impact, consequence, outcome, and the nominal version of impact.

So now that you have understood the basic concept of both the words, we hope that you keep these things mind and consider it while using the words.

Using the right word in the right context will help you save from situations when you might get embarrassed because of such minute things!
