-andry

From three inextricable sources:

the Ancient Greek -ανδρία (-andría), forming abstract nouns of quality or condition from ἀνήρ (anḗr, “man”, “husband”);

Ancient Greek ἀνδρ- (andr-) (andr-: the stem of ἀνήρ (anḗr)) + English -y (suffix forming abstract nouns of quality or condition); and,

the -andry element of polyandry. First attested in 1680.
