Morphology

osmium = osm + ium

The combining form 'osm-' is not a familiar standalone English word and the element name relies on specialized chemical naming, so learners cannot derive the meaning from the parts.

Etymology

Osmium comes from the Greek root osme, which means 'smell'. When chemists first found the metal, a very strong smell from one of its chemicals made them choose that name, and that same name is used today for the hard, very dense metal.
