means A place or state of perfect happiness, beauty, and peace — often imagined as heaven or an ideal earthly garden.

from From Greek 'paradeisos,' an enclosed park or pleasure-garden — but the Greeks borrowed it from Old Persian 'pairidaeza,' literally 'walled around' (pairi-, 'around,' + daeza, 'wall'). Persian kings built lush, walled hunting parks, and the word for those royal gardens traveled into Greek, then into the Greek translation of the Hebrew scriptures, where it came to name the Garden of Eden. So the word for heaven began as a fence.
