پردیس

In Old Persian, paridāiza meant "walled enclosure" or "enclosed garden"—from pari (around) + dāiza (wall, mound). Persian kings built elaborate walled gardens: ordered, irrigated, blooming in the desert. They called them paradīs.

When the Greek historian Xenophon encountered these royal gardens in the 4th century BCE, he borrowed the word as paradeisos (παράδεισος). The Septuagint (Greek Old Testament) used paradeisos for the Garden of Eden.

From that moment, the walled garden became the afterlife. Latin made it paradisus, and every European language followed: paradise, paradis, Paradies, paraiso. A Persian landscaping project became every religion's promise.

The original meaning persists in the word's DNA: paradise is not wilderness but cultivation. Not raw nature but nature ordered by human hands. Heaven, in this etymology, is a garden someone planted.
