Morphology

transuranic + element

This is a straightforward adjectival modification: 'transuranic' describes a property of an 'element' (having atomic number greater than uranium), so the meaning follows directly from the constituent words. The construction is compositional and mirrors common adjective+noun patterns across languages, making it immediately understandable to a learner who knows both constituents.

Etymology

Transuranic element comes from the parts trans meaning 'beyond' and uranic from uranium. So a transuranic element is literally 'beyond uranium', meaning an element with a higher number than uranium on the periodic table, and that is why these elements are usually made in labs and are radioactive.
