Morphology

actinium = actin (opaque) = actin + ium

The suffix '-ium' signals an element, but the stem 'actin' (meaning 'ray' in formation) is technical and not a recognizable base for average learners, so the overall meaning cannot be derived transparently.

Etymology

Actinium comes from the Greek word aktis, meaning 'ray'. It was named because it gives off 'rays' of radiation, so the name helps you remember that actinium is a radioactive element used in research.
