Morphology

iodide = iodine (semi-transparent) = iod + ide

The suffix '-ide' indicates a chemical compound, but the specific meaning requires chemical knowledge.

Etymology

Iodide comes from iodine, a name taken from a Greek word meaning 'violet' because iodine makes a purple gas, and the ending -ide is a common chemical ending, as in chloride or oxide, that shows it is 'combined with' another element, so an iodide is iodine joined to another element.
