From French apathie, from Latin apathīa, from Ancient Greek ἀπάθεια (apátheia, “impassibility”, “insensibility”, “freedom from emotion”), from ἀπαθής (apathḗs, “not suffering or having suffered”, “without experience of”), from ἀ- (a-, “not”) + πάθος (páthos, “anything that befalls one”, “incident”, “emotion”, “passion”). Doublet of apatheia, which was borrowed directly from Ancient Greek.
