Final answer:
An apathetic person is someone who shows or feels no interest, enthusiasm, or concern, typically characterized by indifference or a lack of emotional response.
Step-by-step explanation:
The prefix a- denotes a lack or absence of something, while the suffix -ic turns a word into an adjective, often meaning 'relating to or characterized by.' Therefore, when you combine the root word 'path,' which comes from the Greek word for feeling or suffering, with the prefix a- and the suffix -ic, you get apathetic. An apathetic person would be described as showing or feeling no interest, enthusiasm, or concern. This could be someone who is indifferent, unresponsive, or unemotional towards what might normally excite or engage others.
