Morphology
lutetium = Lutetia (opaque) = lutet + ium
Although '-ium' signals a metallic element, the root 'lutet-' comes from the place name Lutetia and is not meaningful to most learners, so the relation is not obvious.
Etymology
Lutetium is named after Lutetia, the old Latin name for Paris. Scientists who discovered and studied this rare metal worked in Paris, so they gave it a name that reminds us of the city.
