Explanation at your level:

To decrease means to make something smaller. If you have 5 apples and you eat 2, you decrease the number of apples. You have 3 left. It is like turning down the volume on your music. The sound gets smaller. You can use this word when you want to talk about things getting less.

When something decreases, it goes down in number or size. For example, if it stops raining, the amount of water on the ground will decrease. You can use this word at school or home. If you want to save money, you might decrease your spending. It is a very useful word for talking about changes in your life.

The verb decrease is used to describe a reduction in quantity or intensity. It is common in academic and professional English. For instance, 'The company decided to decrease its staff' or 'We must decrease our carbon footprint.' It is often paired with words like 'gradually' or 'significantly' to explain how the change is happening.

In upper-intermediate English, decrease is often used to discuss trends and statistics. It is a precise alternative to 'make smaller.' You might see it in news articles or reports, such as 'The government aims to decrease unemployment rates.' Understanding the difference between the verb and the noun stress is key at this level for natural pronunciation.

At the advanced level, decrease is used to describe abstract concepts or complex systems. You might say, 'The policy served to decrease the tension between the two nations.' It is frequently used in formal writing to maintain an objective, professional tone. It is also common in scientific contexts to describe the decay or reduction of variables in an experiment.

At the mastery level, decrease is understood as part of a broader lexical field including diminish, dwindle, and wane. While these words are synonyms, they carry different nuances. Decrease is the most neutral and widely applicable term. In literary contexts, you might use it to describe the waning of influence or the slow fading of a memory, showcasing your ability to choose the most appropriate register for your writing.

  • Decrease means to make something smaller.
  • It is both a noun and a verb.
  • Stress changes based on the part of speech.
  • It is a very useful word in professional settings.

When you use the word decrease, you are talking about the act of making something smaller. Think of it as the opposite of 'increase.' Whether you are talking about the number of cookies in a jar or the speed of a car, decrease is the perfect verb to describe that downward movement.

It is a very versatile word that works in almost any situation. You can use it in a math class, a science lab, or just while talking about your daily chores. It is a neutral, professional-sounding word that fits well in both casual chats and serious business reports.

Remember, when you decrease something, you are intentionally or naturally causing it to have less value or volume. It is a fundamental concept in our world, helping us describe change and progress in a clear, concise way.

The word decrease has a long journey through history. It comes from the Old French word descreistre, which itself was born from the Latin word decrescere. This Latin root is a combination of de- (meaning 'down' or 'away') and crescere (meaning 'to grow').

Essentially, the word literally means 'to grow down' or 'to stop growing.' It entered the English language around the 14th century. It has remained remarkably consistent in its meaning over the last 700 years, which is quite rare for such common words!

Interestingly, the related word crescent (like the moon shape) shares that same Latin root crescere. While a crescent moon is 'growing,' to decrease is to do the exact opposite. It is fascinating how these linguistic cousins tell us so much about how we perceive growth and change in the natural world.

Using decrease is straightforward, but it is often paired with specific words to sound more natural. You will frequently hear people talk about a significant decrease or a gradual decrease. These adjectives help define how quickly or how much something is shrinking.

In a formal setting, like a research paper, you might say, 'The data shows a decrease in temperature.' In a more casual setting, you might say, 'We need to decrease the amount of sugar we eat.' The word is very flexible.

Be careful not to confuse it with 'reduce,' which is a synonym. While they are often interchangeable, 'reduce' can sometimes imply a more active, manual effort, whereas 'decrease' can happen naturally over time. Both are excellent choices for clear communication.

While decrease itself is a formal verb, it appears in many common expressions. 1. On the decrease: Meaning something is currently getting smaller (e.g., 'The storm is on the decrease'). 2. Decrease in value: Often used in finance to describe depreciation. 3. Show a decrease: A common phrase in business reports. 4. Marked decrease: Used when the change is very obvious. 5. Gradual decrease: Used when the change happens slowly over a long period.

As a verb, decrease is regular, making its past tense decreased and its present participle decreasing. The stress pattern is important: when used as a verb, the stress is on the second syllable (de-crease). When used as a noun, the stress shifts to the first syllable (de-crease).

It is a transitive verb, meaning it usually takes an object (e.g., 'Decrease the heat'). You can also use it intransitively, where the subject itself is shrinking (e.g., 'The population decreased'). It rhymes with words like cease, lease, peace, piece, and geese.

In terms of IPA, the British and American pronunciations are quite similar, usually transcribed as /dɪˈkriːs/. Mastering this stress shift between the noun and verb forms is a great way to sound more like a native speaker.
