Morphology

einsteinium = Einstein (transparent) = einstein + ium

Standard chemical-naming pattern: a proper name + -ium signals an element named after the person, so the relation is clear to learners familiar with element names.

Etymology

Einsteinium is named after the famous scientist Einstein, and the ending -ium shows it is a chemical 'element'. It was first found in the debris of a hydrogen bomb and is made in labs by hitting plutonium with neutrons, so Einsteinium is a rare, man-made, highly radioactive element.
