Morphology

tetraiodothyronine = iodothyronine (opaque) = tetra + iodo + thyron + ine

The term is a technical chemical name built from combining forms ('iodo-', 'thyron-') that are not everyday words, so the meaning is not recoverable by an average B1 learner.

Etymology

Tetraiodothyronine comes from the parts tetra- 'four', iodo- 'iodine', and thyro- 'thyroid', so the name pictures a thyroid chemical with four iodine atoms. That's why tetraiodothyronine, also called thyroxine, is the hormone from the thyroid that helps control how fast your body uses energy.
