Origin: 1350–1400; Middle English redounden < Middle French redonder < Latin redundāre to overflow, equivalent to red-red- + undāre to surge (derivative of unda wave; compare undulate); compare redundant
1382, "to overflow," from O.Fr. redonder "overflow, abound" (12c.), from L. redundare "to overflow" (see redundant). Meaning "to flow or go back" (to a place or person) is from 1382; hence "to rebound" (c.1500), and "to contribute to" (the credit, honor, etc.), c.1500.
