decrease
This word focuses on the quantitative aspect of reduction. It is a neutral, clinical term often found in scientific reports, financial statements, or mathematical contexts to describe a downward trend. It implies a measurable change rather than a sudden disappearance. While a decline can suggest a loss of quality or a moral fall, a decrease is strictly about the volume or number. It carries a sense of precision and objectivity, making it the standard choice for data-driven observations.
Countable when referring to a specific instance of reduction (a decrease in price). Uncountable when referring to the general process of becoming smaller.
意味

"The company decided to decrease spending on advertising."
To become smaller in size, amount, or intensity.
"The temperature began to decrease as the sun set."
