Morphology

levothyroxine = thyroxine (opaque) = levo + thyroxine

The word is a technical drug name built from the stereochemical prefix 'levo-' and the technical root 'thyroxine', which is unlikely to allow a B1 learner to infer the medical meaning.

Etymology

Levothyroxine comes from two parts you can see: levo- meaning 'left' and thyroxine, the name of the thyroid hormone. A helpful way to remember it is that this medicine is the 'left' or correct form of thyroxine used to replace the thyroid hormone the body does not make.
