Morphology

toxin = toxic (transparent) = tox + in

The relation to the common adjective 'toxic' is direct and the suffix '-in' signals a substance, so learners who know 'toxic' can infer 'toxin' as a poisonous substance.

Etymology

The word toxin comes from an old Greek word toxikon, meaning 'poison for arrows', and from toxon, 'bow'. So a toxin is a natural 'poison' made by living things like plants, animals, or bacteria, which is why we also use toxic to mean 'harmful'.
