rain, snow, and similar water
Water that falls from the sky as rain, snow, sleet, or hail.
用法模式：
precipitation falls on [place]
常见错误：
Learners sometimes treat "precipitation" as countable (e.g., *"many precipitations") or confuse it with "participation" because they sound similar. "Precipitation" in this weather sense is usually uncountable and refers to rain, snow, etc., not to taking part in something.
近义词
rainfall (Refers only to rain, not to snow, sleet, or hail, and is slightly more common in everyday speech.)

用法模式：
the [period] precipitation in [place] is [amount]
常见错误：
Learners may use "rain" instead of "precipitation" in scientific or geographic contexts where snow and other forms are also included, or they may not realize that this sense focuses on the measured amount, not just the event itself.
近义词

solid forming from a solution
In chemistry, when a solid forms in a liquid because of a reaction or change, or the solid that appears.
用法模式：
precipitation of [substance] from [solution]

Learners often think "precipitation" only means rain or snow and may not realize it has a separate, technical meaning in chemistry. They may also confuse the noun "precipitation" with the verb "to precipitate" and use the wrong form in sentences.
近义词
crystallization (Similar, but usually refers specifically to the formation of crystals, while precipitation can produce non-crystalline solids as well.)

great haste or rashness
Doing something very fast and without enough thinking.
用法模式：
to act with precipitation
常见错误：
Learners may misinterpret this formal sense as the weather meaning if they have not seen it before. It is rare in modern speech and mostly found in formal or literary writing, so learners should rely on more common words like "haste" or "rush" in everyday use.
近义词
haste (More common and general; "precipitation" sounds more formal and often suggests poor judgment.)
