Morphology

triiodothyronine = iodothyronine (opaque) = tri + iodo + thyronine

The immediate base 'iodothyronine' is a specialized chemical name built from technical combining forms (iodo- + thyronine) that are not transparent to average learners.

Etymology

Triiodothyronine breaks into tri- 'three', iodo- from iodine 'a purple element', and thyroid 'neck gland'. So triiodothyronine is the thyroid hormone that has three iodine atoms and helps control how the body uses energy.
