redundant

redundant: [17] Etymologically, something that is redundant ‘overflows’ because there is too much of it. The word comes from the present participle of Latin redundāre ‘flow back, overflow’ (source also of English redound [14]). This was a compound verb formed from the prefix re- ‘back, again’ and undāre ‘rise in waves, surge’, a derivative of unda ‘wave’ (source of English undulate).
=> redound, surround, undulate
