Understanding the Word "Decrease"
Whether you are talking about the temperature outside, the amount of sugar in a recipe, or the speed of a car, you will often find yourself needing to describe when things get smaller or lower. The word decrease is the perfect tool for these moments. To decrease means to make something smaller in size, amount, intensity, or degree. Mastering this word will help you communicate more precisely in both your academic writing and everyday conversations.
Meanings and Usage
The word decrease functions as both a verb and a noun. Understanding the subtle difference between these two roles is key to using the word correctly.
As a Verb
When used as a verb, decrease describes an action. It means to cause something to become smaller or to undergo a reduction. You can decrease something yourself, or it can decrease on its own.
- "The government hopes to decrease unemployment rates by creating new jobs."
- "As the sun sets, the temperature will naturally decrease."
- "Please decrease the volume on the television so we can study."
As a Noun
As a noun, decrease refers to the downward change itself or the result of that change. In this form, it is often preceded by an article like "a" or "the."
- "There has been a significant decrease in the number of people smoking."
- "The doctor noted a sudden decrease in the patient's blood pressure."
- "We are hoping for a decrease in the cost of electricity next month."
Grammar Patterns and Common Phrases
To use decrease like a native speaker, keep these common grammatical patterns in mind:
- Decrease by/in: When using the verb, we often pair it with "by" to show the amount, or "in" to show the area being affected. "The company decreased its expenses by 10 percent."
- Common Collocations: You will frequently hear the word paired with specific terms. Common phrases include a sharp decrease, a gradual decrease, or to see a decrease.
- Antonyms: The direct opposite of decrease is increase. Remembering this pair makes it easier to track changes in graphs, charts, and scientific experiments.
Common Mistakes
One common mistake is confusing the noun and verb forms in speech. When decrease is a verb, the stress usually falls on the second syllable (de-CREASE). When it is a noun, the stress shifts to the first syllable (DE-crease). Be careful to observe this change in rhythm when speaking.
Another error involves preposition usage. Learners sometimes say "decrease to" when they mean "decrease by." If you want to show how much something changed, use "by." If you want to show the final result, use "to." For example: "The price decreased by five dollars to twenty dollars."
Frequently Asked Questions
Is "decrease" formal or informal?
Decrease is a neutral word. It is perfectly acceptable in casual conversation, but it is also common in formal contexts like business reports, scientific papers, and academic essays.
Can I use "decrease" for people?
Usually, we use decrease for quantities, amounts, or measurable values. If you are talking about the number of people in a group, it is correct. However, you should not say "the person decreased" to mean they lost weight; instead, use "lost weight" or "became thinner."
What is the difference between "decrease" and "reduce"?
These words are often synonyms. However, reduce usually implies an active, intentional effort to lower something, while decrease can happen either actively or naturally on its own.
Conclusion
The word decrease is a versatile and essential part of the English language. By learning how to distinguish between its role as a verb and a noun, and by practicing how it interacts with other words, you can make your descriptions much more accurate. Whether you are tracking scientific data or simply managing your daily schedule, decrease will help you express changes clearly and effectively.
