Morphology

thyroxin = thyroid (semi-transparent) = thyro + in

The combining form 'thyro-' clearly relates to 'thyroid' and the suffix '-in' signals a substance/hormone, but the precise biochemical role (regulating metabolism) is specialized knowledge beyond simple morphological inference.

Etymology

Thyroxin comes from thyroid, a name from Greek that means 'shield', because the thyroid gland looks like a small shield at the front of the neck. Thyroxin is the hormone made by that gland and it controls how fast the body uses energy, so the name links the hormone to the 'shield' gland that makes it.
