Root Explanation

Anaphylactic → It is formed from "ana-" (meaning against) and "phylaxis" (from Greek "phylaxis", meaning protection). The term describes a severe reaction that is against the body's normal protective responses.

Memory Tip

Think of 'against' ('ana-') the body's 'protection' ('phylaxis') — that's why anaphylactic refers to a severe reaction that opposes normal protection.
