Morphology

hahnium = Hahn (semi-transparent) = hahn + ium

The suffix '-ium' clearly signals a chemical element, but identifying the specific person 'Hahn' requires specialized knowledge, so the name-based referent is not fully deducible by general learners.

Etymology

The word hahnium comes from the name of the German scientist Otto Hahn, so it was used as the name for chemical element 105 to honor him, much like einsteinium is named after Einstein. That's why hahnium is a 'former name' for the element now called dubnium.
