The two words, affect and effect, are often used interchangeably. Since most people don’t give it much thought, it is used incorrectly, much more than almost any other pair of words in the English language.
Ironically, both words could not be more different in definition. But, even though they have very distinct meanings, they are so close in function that it’s not surprising people get confused between them.
Although it’s easy to use them incorrectly, it’s just as easy to memorize the difference once and for all. So here’s everything you need to know to do exactly that.
The Difference Between Effect and Affect
Unless you are a native English speaker, differentiating between affect vs. effect can be quite tricky. Some people even think using these words interchangeably won’t make a difference, but that’s a completely wrong thought. You need to learn the difference and how they can be used in different sentence structures.
The main difference arises in the way they’re most commonly used. The word “effect” is mostly used as a noun in a sentence, whereas “affect” is often used as a verb. Even though there might be exceptions to this rule, you can still use this trick when confused.
Another great trick to remembering the difference is that “affect” comes first in the alphabetic order, and similarly, an action (affect) has occurred before any result (effect).
Why Are They So Confusing?
Although they might not seem like much, there are a few major reasons that make people forget which word is correct for their context. Let’s highlight some of these confusing factors.
Correct Usage and Exceptions
As is the case with other English words, there are exceptions to the norms when it comes to the words affect and effect. These exceptions are one of the main reasons why people get confused over them.
The exception, in this case, would be “effect” being used as a verb in a sentence and “affect” being used as a noun. The verb, more precisely known as transitive for “effect”, means to cause something to happen or bring about.
- The prime minister effected multiple policy changes.
However, the verb form of “effect” is more common than the noun form of “affect”, which is used in psychological jargon. On the other hand, the noun “affect,” having stress on the first syllable (AFF-ect), means a mental state.
- The doctor noted the patient’s abnormal affect.
The second major reason people get confused about these words is their similar-sounding pronunciation since they are homonyms or sound-alike words. Typically people pronounce them both in the same way, which makes sense because even their correct pronunciation sounds alike.
If you want to pronounce them right, the trick is to stress the first syllables of each word. For affect, you have to say “ah-ffect”. While for effect, it’s more of an “ee-ffect”.
Examples of How to Use Them
Meaning of Effect
The word “effect” means the outcome of an action that usually follows a cause. You might have heard people use “side effects” when referring to medication. In this sense, “effect” is used to denote the end result that occurs as a consequence of taking certain medications.
Besides being used as a noun, it also has a verb form that is not commonly used. The verb form means “to cause something to happen.”
Below are some examples of how to use “effect” in a sentence.
- As a Noun: The effects of the thunderstorm were devastating for the village.
- As a Verb: The new manager is bound to effect positive changes in the workplace.
Meaning of Affect
Most commonly, this word is used to describe something changed or influenced by another factor. It is basically an action word that emphasizes a change to something. The change can be in a positive or negative sense.
As mentioned, it is most commonly used as a verb and less commonly as a noun. The noun form is used mainly in psychological contexts to refer to the facial expressions and vocal intonations to enhance emotion.
Below are examples to help you better understand using “affect” in a sentence.
- As a Verb: The lady must have affected them to get that kind of emotional response.
- As a Noun: the young man’s facial expressions had a humorous affect.
