Root Explanation

Autoimmune → It is formed from "auto-" (from Greek "αὐτός" meaning self) and "immunis" (from Latin meaning exempt or free from). The word describes a condition where the immune system mistakenly attacks the body's own cells, hence acting against itself.

Memory Tip

Think of 'self' ('auto-') and 'exempt' ('immunis') to remember that autoimmune refers to the immune system acting against its own body.
