Reduce vs. Decrease: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Updated on October 2, 2023
Reduce means to make something smaller in size, amount, or extent, usually with intent, while decrease refers to the process of diminishing in size, amount, or extent, possibly without intent.

Key Differences
Reduce and decrease, while similar, imply subtle variations in their usage and context. The term reduce often involves an element of intent or deliberate action, often denoting an active effort to bring down the quantity, size, or degree of something. It can also carry a broader sense, referring to simplifying or breaking down into components. On the other hand, decrease typically describes the process or result of diminishing and may not necessarily involve intentional action. It can occur naturally or as a result of other influences and generally signifies a reduction in size, amount, number, or extent.

In application, when one chooses to reduce waste, it implies a conscious effort to limit waste production, which might involve recycling or using fewer resources. Conversely, when we observe that daylight hours decrease in winter, we are describing a natural, cyclical, and unintentional process of reduction in the amount of daylight. Here, decrease denotes a phenomenon occurring without direct human intervention or deliberation, highlighting its more passive or observational nature.

Speaking about their connotations, reduce tends to reflect more on the actions or processes that lead to a lesser amount or size, and it often emphasizes the methodology or approach utilized to achieve a smaller quantity or degree. In contrast, decrease is more focused on the outcome or the state of being reduced and is less concerned with the methods or actions leading to such a state, making it a more neutral and descriptive term.

These words are versatile and can be used in various contexts, be it mathematical, scientific, or everyday language. In mathematics, to reduce a fraction means to simplify it to its lowest terms, highlighting a process or action. To say a value decreases in mathematics simply illustrates that the value is getting smaller, reflecting a state or condition.

From a grammatical perspective, both words can be used as verbs, and decrease can also be used as a noun, referring to the process or amount by which something gets smaller. Reduce often emphasizes action and process, while decrease emphasizes state and result.
