Precursor Definition & Meaning

A "precursor" is a noun that refers to something that comes before and often serves as a forerunner or an early indication of a more significant or subsequent event, development, or phenomenon. It is a term used to describe a predecessor or something that precedes and contributes to the creation or understanding of something else.

For example, if a new scientific discovery builds upon earlier research, that earlier research is considered a precursor to the new discovery. Similarly, an invention or technological innovation may have precursors in the form of earlier experiments or developments.

In a broader sense, a precursor can also refer to a sign or indication that something is about to happen or change in a particular way. For example, a sudden drop in temperature can be a precursor to a snowstorm.
