Morphology

tri-iodothyronine = iodothyronine (semi-transparent) = tri + iodo + thyronine

Formally analyzable as 'tri-' + 'iodothyronine', but the combining forms are technical and may not be known to average learners.

Etymology

Tri-iodothyronine breaks into parts: tri- meaning 'three', iodo- meaning 'iodine', and thyronine meaning 'thyroid', the part in the neck that makes hormones. So tri-iodothyronine, often called T3, is literally a thyroid hormone with three iodine atoms that helps control the body's metabolism.
