-machy
in actual use -omachy (ˈɒməkɪ), represents the ending -µαχία of certain Gr. ns. with the general sense ‘fighting, warfare’, which are derivatives of adjs. in -µάχος with the general sense ‘that fights’; the root is that of µάχεσθαι to fight, µάχη battle. Of the Eng. words with this ending, some are adoptions of actual Gr. words, as logomachy; others have been formed from Gr. elements on Gr. analogies, as angelomachy; the ending has not been employed in hybrid formations.
