Root Explanation

Spermicide → It is formed from "sperma" (from Greek σπέρμα, meaning seed) and "-cide" (from Latin "caedere", meaning to kill). The word "spermicide" refers to a substance that kills sperm, thus preventing fertilization.

Memory Tip

Think of 'seed' ('sperma') being 'killed' ('-cide') — that's why spermicide is a substance that kills sperm.
