IPA: /ˈænəˌtaɪkɪn/

A type of poison produced by certain blue-green algae that can affect the nervous system.
The presence of anatoxin in the water supply raised concerns about public health.
Anatoxin is formed from "ana-" (meaning up or back) and "toxicum" (from Greek "toxikon", meaning poison). The word refers to a substance that counteracts or neutralizes a toxin, hence the meaning of an antitoxin.
Think of 'up' or 'back' ('ana-') as something that helps you recover from 'poison' ('toxicum'). This helps you remember that anatoxin is related to neutralizing toxins.
