Old English begeondan "on the other side of, from the farther side," from be- "by," here probably indicating position, + geond "yonder" (prep.); see yond. A compound not found elsewhere in Germanic. From late 14c. as "further on than," 1530s as "out of reach of." To be beyond (someone) "to pass (someone's) comprehension" is by 1812.
