Root Explanation

Sublethal is formed from "sub-" (meaning under or below) and "lethal" (from Greek "lethalis", meaning deadly). The word describes something that is below the level of causing death, indicating a non-fatal effect.

Memory Tip

Think of 'sub-' meaning 'under' and 'lethal' meaning 'deadly' — so sublethal refers to something that is not deadly or below the level of causing death.
