a combining form occurring in loanwords from Greek, where it meant “suffering,” “feeling” (antipathy; sympathy
); in compound words of modern formation, often used with the meaning “morbid affection,” “disease” (arthropathy; deuteropathy; neuropathy; psychopathy
), and hence used also in names of systems or methods of treating disease (allopathy; homeopathy; hydropathy; osteopathy
). Cf. -path, -pathia.
