Morphology
androstenedione = androst + ene + dione
The word is built from specialized Greek/chemical combining forms (androst- + -ene + -dione) that are not productive or recognizable to an average B1 learner, so the meaning cannot be derived from the components.
Etymology
Androstenedione comes from the Greek root andro- meaning 'male' and the chemical ending -dione meaning 'two' oxygen groups. So the name reminds you it is a male-related hormone the body uses to make testosterone and estrogen.
