Precipitate
Precipitate as a verb, it means to cause something to happen suddenly or unexpectedly. It’s like when something occurs in a quick and abrupt manner, often without much warning or preparation. An example could be a scientific experiment. If you mix two chemicals together and they react immediately, producing a visible change, you could say that the mixing of the chemicals precipitated a chemical reaction. The reaction occurred rapidly and without delay.
In a broader sense, precipitate can also refer to taking impulsive or rash actions without thinking about the consequences. For instance, if you decide to quit your job without having a backup plan, you might precipitate financial difficulties.
