Relating to the time before the biblical fall of Adam and Eve, often used to describe an idealized state of innocence or purity.
Many people long for a prelapsarian world where innocence and harmony prevailed before human sin.
Prelapsarian → It is formed from "pre-" (meaning before) and "lapsus" (from Latin, meaning fall or slip). The term refers to the state of humanity before the fall from grace, specifically before Adam and Eve's transgression in the Garden of Eden.
Think of 'pre-' meaning before and 'lapsus' meaning fall — this helps you remember that prelapsarian refers to the time before the fall from grace.
