Etymology Origin:
The word contagious originates from Latin contagiosus, derived from contagio (contact, touching). The root tangere (to touch) is central, reflecting the idea of transmission through physical contact. Over time, the meaning expanded metaphorically to include non-physical spread (e.g., emotions). The prefix con- emphasizes the collective aspect of transmission.
