Morphology
unnilquadium = un + nil + quad + ium
The word is an IUPAC systematic chemical name composed of numeric combining forms plus the element suffix '-ium'; these are specialized, non-productive morphemes for general English learners and thus not transparently interpretable.
Etymology
The word unnilquadium comes from number parts: un- 'one', nil- 'zero', and quad- 'four', plus the ending -ium, like in calcium, which is common for metals. As a helpful memory hook, it literally reads 'one-zero-four', so it was a temporary name for element 104 before the official name rutherfordium.
