Morphology

iodine = iod + ine

The element name is built from the combining form 'iod-' (not a standalone English word) plus the chemical suffix '-ine'; learners cannot derive the meaning from familiar English bases.

Etymology

Iodine comes from the Greek word ioeides meaning 'violet-coloured', like the colour 'violet', because the element makes a purple vapour when heated; so the name points to its deep purple-black colour which you see in the element used in medicine, photography, and dyes.
