probably akin to the base of ἀγορά (through the idea of collecting one's faculties); to waken (transitively or intransitively), i.e. rouse (literally, from sleep, from sitting or lying, from disease, from death; or figuratively, from obscurity, inactivity, ruins, nonexistence):--awake, lift (up), raise (again, up), rear up, (a-)rise (again, up), stand, take up.
