Morphology

anatoxin = toxin (semi-transparent) = ana + toxin

The component 'toxin' is clear, but the prefix 'ana-' here is a specialized technical formation (meaning a detoxified or altered toxin in immunology) that is not obvious to average learners.

Etymology

Anatoxin joins the prefix ana- and the familiar word toxin, and a helpful way to remember it is that ana- can mean 'changed' or 'made again', so it points to a toxin that has been changed. So an anatoxin is a toxin made harmless but still able to make the body build immunity, which is why it is used in some vaccines.
