pandemic

the word pandemic is a modern formation derived from classical greek components. it combines πᾶν (pan), meaning "all", with δῆμος (dēmos), meaning "people" or "population", and the adjectival suffix -ικός (-ikos). the literal construction yields "of or pertaining to all the people". this term was historically used in medicine to distinguish diseases affecting an entire population or a very wide geographical area from those that are "epidemic" (upon the people) in a more localized sense or "endemic" (within the people) to a particular region. the logic of the word perfectly captures its modern meaning: a disease outbreak that transcends local boundaries to affect people on a global scale.
