What does precursor mean?
A precursor is an earlier person, object, stage, or event that anticipates or helps bring about something more important that follows. The term is especially common in historical, scientific, and cultural writing: a novel may be called a precursor of a later genre, while an early scientific discovery may be described as a precursor to a modern technology. “Precursor” differs from “predecessor” in emphasis: a precursor is normally connected with development, influence, or the arrival of something later, whereas a predecessor may simply occupy an earlier position in a sequence. The noun is formal but widely understood, and “precursor to” is particularly idiomatic, although “precursor of” is also standard. It can apply to people, physical objects, and abstract concepts, such as early electronic computers or an artist's early experiments. Because the word comes from imagery of running ahead, it captures the idea of going before something else and leaving a sign of its coming. That combination of sequence and significance makes “precursor” useful when an earlier development mattered not merely because it came first, but because it pointed toward or made possible what followed.

Where does precursor come from?
The word entered English from Latin during the late Middle English period. Latin praecursor means “forerunner” and was formed from praecurrere, “to run before,” combining prae-, “before,” with currere, “to run.” The same Latin root produced words such as cursor, cursive, current, and recur.
