late Old English orceard "fruit garden," earlier ortgeard, perhaps reduced from wortgeard, from wort (Old English wyrt "vegetable, plant root") + geard "garden, yard" (the word also meant "vegetable garden" until 15c.); see yard (n.1). First element influenced in Middle English by Latin hortus (in Late Latin ortus) "garden," which also is from the PIE root (*gher- (1) "to grasp, enclose") that yielded yard (n.1).
