Morphology

diarchy = diarch (semi-transparent) = diarch + y

Formationally regular (diarch + -y = system of rule), but the combining form 'di-' and the rare base 'diarch' may not be familiar to average learners.

Etymology

Diarchy comes from Greek parts di- meaning 'two' and -archy meaning 'rule', the same root as in monarch and anarchy, so a diarchy is a government 'ruled by two' people.
