Redevelop → It is formed from "re-" (meaning again) and "develop" (from Old French *desveloper*, meaning to unwrap or unfold). The word "redevelop" means to develop something again or to improve it after it has been previously developed.
Think of 'developing' something 'again' — 're-' means again, and 'develop' means to unfold or improve.
