Morphology
diprotium + monoxide
The term is systematically compositional: 'monoxide' denotes one oxygen and 'diprotium' would mean two protium (hydrogen) atoms, so the parts together denote H2O. However, this relies on specialized chemical nomenclature (the prefix di- and the rare term 'protium'), knowledge that a typical B1 learner is unlikely to have, making the expression only partially predictable.
Etymology
Diprotium monoxide is a very formal chemical name. The parts diprotium ('two common hydrogens') and monoxide ('one oxygen') literally describe 'H2O', so diprotium monoxide simply means 'water'.
