First things first. "Primeval" comes from the Latin words primus, meaning "first, and aevum, meaning "age." In Latin, those terms were brought together to form "primaevus," a word that means "of or relating to the earliest ages." Other English words that descend from "primus" include "prime" and "primary," "primordial" (a synonym of "primeval"), and "primitive." "Primus" also gave rise to some terms for folks who are number one in charge, including "prince" and "principal."
