Summary: The Greek root word *path* can mean either "feeling" or "disease." This word root is the word origin of a number of English vocabulary words, including sym[*path*]y, a[*path*]y, [*path*]ological, and socio[*path*]. An easy way to remember these different meanings is that a sym[*path*]etic person "feels" pain with another, whereas a psycho[*path* does twisted things because he has a "diseased" mind.
