Etymology
the word perpetuity originates from the latin "perpetuitas", which itself derives from "perpetuus", meaning "continuous, unbroken". "perpetuus" is a compound of the intensive prefix "per-" (through) and the root "petere" (to seek, go towards), conveying the sense of "going through to the end" or "seeking completion". this literal notion of uninterrupted pursuit evolved into the abstract concept of unending duration. entering english via old french "perpetuité" in the late middle ages, it solidified its legal and general meanings pertaining to eternal or indefinite continuation.
