Morphology
rotenone = roten + one
The word is a specialized chemical name: although it contains the chemical suffix '-one', the stem 'roten' is not a productive English base learners can use to infer meaning without specialist knowledge.
Etymology
Rotenone comes from a local name roten for the plant 'roots' where it was first found, plus the chemical ending -one that marks many chemicals. So it is the chemical from those roots, which helps you remember why rotenone is used as a natural insect and fish poison in gardens.
