Knowing when to use affect or effect in a sentence can be a challenge. These words are examples of homonyms. Homonyms are words that are similar, but have very different meanings. Other examples of homonyms are two/to/too, accept/except, and there/their/they’re.
Meaning of Affect and Effect
In order to understand the correct situation in which to use the word affect or effect, the first thing one must do is have a clear understanding of what each word means.
- Affect is a verb. It means to produce a change in or influence something.
- Effect is a noun that can also be used as a verb. It means a change that occurred. When an “s” is added, “effects” means personal belongings.
Now that we have the two definitions, how do we know which word to use? Here are a few suggestions to keep in mind:
1. Affect can be used as a noun to describe facial expression.
- Example: The young man with schizophrenia had a flat affect.
- Example: The woman took the news of her husband’s sudden death with little affect.
2. Affect can also be used as a verb. Use it when trying to describe influencing someone or something rather than causing it.
- Example: How does the crime rate affect hiring levels by local police forces?
- Example: The weather conditions will affect the number of people who come to the county fair this year.
1. If you are talking about a result, then use the word “effect” as a noun.
- Example: What effect did the loss have on the team?
2. It is appropriate to use the word “effect” if one of these words is used immediately before the word: “into”, “on”, “take”, “the”, “any”, “an” as well as “or.”
- Example: The prescribed medication had an effect on the patient’s symptoms.
- Example: In analyzing a situation, it is important to take the concepts of cause and effect into consideration.
3. If you want to describe something that was caused or brought about, the right word to use is effect; but, as shown in this example, it would be a verb.
- Example: The new manager effected some positive changes in the office. (This means that the new manager caused some positive changes to take place in the office.)
