Redound → It is formed from "re-" (meaning again) and "undare" (from Latin, meaning to flow). The word "redound" means to flow back or have an effect again, often in a positive or beneficial way.
Think of something that 'flows back' ('undare') again ('re-') — that's why redound means to have a positive effect that returns.
