late 12c., "Garden of Eden," from Old French paradis "paradise, Garden of Eden" (11c.), from Late Latin paradisus, from Greek paradeisos "park, paradise, Garden of Eden," from an Iranian source, cf. Avestan pairidaeza "enclosure, park" (Modern Persian and Arabic firdaus "garden, paradise"), compound of pairi- "around" + diz "to make, form (a wall)."
The first element is cognate with Greek peri- "around, about" (see per), the second is from PIE root *dheigh- "to form, build" (see dough).
The Greek word, originally used for an orchard or hunting park in Persia, was used in Septuagint to mean "Garden of Eden," and in New Testament translations of Luke xxiii:43 to mean "heaven" (a sense attested in English from c.1200). Meaning "place like or compared to Paradise" is from c.1300.
A place or state of pure happiness. Christians have identified paradise both with the Garden of Eden and with heaven.
a Persian word (pardes), properly meaning a "pleasure-ground" or "park" or "king's garden." (See EDEN.) It came in course of time to be used as a name for the world of happiness and rest hereafter (Luke 23:43; 2 Cor. 12:4; Rev. 2:7). For "garden" in Gen. 2:8 the LXX. has "paradise."
in religion, a place of exceptional happiness and delight. The term paradise is often used as a synonym for the Garden of Eden before the expulsion of Adam and Eve. An earthly paradise is often conceived of as existing in a time when heaven and earth were very close together or actually touching, and when humans and gods had free and happy association. Many religions also include the notion of a fuller life beyond the grave, a land in which there will be an absence of suffering and a complete satisfaction of bodily desires. Accounts of a primordial earthly paradise in the higher religions range from that of a garden of life (Judaism, Christianity, Islam) to that of a golden age of human society at the beginning of each cycle of human existence (Buddhism, Hinduism). A final state of bliss is variously conceived of as a heavenly afterlife (Islam, Christianity), union with the divine (Hinduism), or an eternal condition of peace and changelessness (Buddhism).
