What does precipitant mean?
A precipitant is, most commonly in chemistry, a substance that causes another material to come out of a solution as a solid. In formal general English, the word can also mean an event or influence that brings about another development, especially one that happens quickly. As an adjective, it describes action that is abrupt, hurried, or excessively swift. The term is useful because it emphasizes both the role of a trigger and the suddenness of the resulting process. In a laboratory, adding a precipitant can make a dissolved substance visibly separate; in political, social, or historical discussion, a precipitant can identify the immediate event that set a larger change in motion. Its register varies by sense: chemical usage is standard in science, while the broader noun and adjective tend to sound formal or literary.
A substance that causes another substance to separate from a solution, especially by forming a solid.
"The clear solution became cloudy when the precipitant was added."
Standard technical terminology in chemistry and related sciences.

"The dispute precipitated a crisis in the negotiations."
Formal; often used with events, crises, actions, or developments.
Hasty, abrupt, or done with excessive speed.
"The board criticized the precipitant closure of the program."

The plural is used for chemical substances that cause precipitation and, in formal general usage, for events or influences that trigger developments.

In chemistry, a precipitant is the substance that makes a dissolved solid appear, turning an invisible solution into visible matter.

Where does precipitant come from?
The word comes from Latin praecipitans, a present participle associated with praecipitare, meaning to hasten or precipitate. The Latin verb developed from roots referring to throwing or casting forward, and English borrowed it in senses involving both rapid action and the formation of a precipitate in chemistry. Related English forms include precipitate, precipitation, and precipitous, which preserve the ideas of hastening, falling or settling, and steepness.
