Root Explanation
Propagate → It is formed from "pro-" (meaning forward) and "pagare" (meaning to set or to lay). The word "propagate" means to set forth or spread something forward, such as ideas or plants.
Memory Tip
Think of 'setting something forward' — 'pro-' means forward, and 'pagare' means to lay down. This helps you remember that propagate means to spread or reproduce something.
