How Apathy Differs From Impassivity and Indifference

Apathy, impassivity, and indifference all denote a lack of responsiveness to something that might normally excite interest or emotion. Apathy suggests a puzzling or deplorable inertness or lack of passion, as in “the problem of continued voter apathy.” Impassivity stresses the absence of any external sign of emotion in action or facial expression, as in “teachers frustrated by the impassivity of their students.” Indifference connotes a lack of interest in or concern about something, as in “the company’s apparent indifference to the needs of its employees.”

The Greek Origins of Apathy

There's no reason to be uncaring about the origins of apathy—though there is a clue to the word's beginnings in this sentence. Apathy was borrowed into English in the late 16th century from Greek apatheia, which itself comes from the adjective apathēs, meaning "without feeling." Apathēs, in turn, was formed by combining the negating prefix a- with pathos, meaning "emotion." Incidentally, if you've guessed that pathos is the source of the identically spelled noun in English (meaning either "an element in experience or in artistic representation evoking pity or compassion" or "an emotion of sympathetic pity"), you are correct. Pathos also gave us such words as antipathy, empathy, sympathy, pathetic, and even the archaic word pathematic ("emotional").
