What this suffix does
The suffix -pathy comes from Greek "pathos" (feeling, suffering, disease) and appears in two types of word:
1. Emotional or perceptual states: empathy (feeling what another feels), sympathy (feeling alongside another), telepathy (feeling from a distance).
2. Medical conditions or disorders: neuropathy (nerve disease), cardiopathy (heart disease), sociopathy (antisocial personality disorder).
Spanish: empathy → empatía, sympathy → simpatía, neuropathy → neuropatía.
Empathy vs sympathy: a crucial distinction
One of the most important distinctions in emotional English:
Sympathy /ˈsɪmpəθi/ = you feel sorrow or solidarity for someone, looking in from outside their experience. "I feel sympathy for your loss."
Empathy /ˈɛmpəθi/ = you put yourself inside their experience, feeling what they feel. "I empathize — I went through the same thing."
Rule: sym- = alongside (from outside); em- = within (inside the other's experience). In modern English, "empathy" is the more valued term in mental health, leadership and relationship contexts.
