pandemic (pan-DEM-ik) - adj., (of a disease) epidemic over a large area, prevalent throughout an entire country, continent, or the world; (in general) widespread, general. n., a disease prevalent throughout an entire country, continent, or the world.
This prefix, pan-, is from Ancient Greek, where it was also a prefix meaning all/every -- the stem here is also from Ancient Greek, dêmos, the common people/the population, and put together pándēmos meant "of or belonging to all the people." Its application to diseases in English dates to the 1650s (the noun use is from the 1830s). Closely related is epidemic, meaning prevalent throughout a community, so more localized than a pandemic, and endemic, meaning constantly present at a baseline level, so occurring at lower levels than a epidemic/pandemic. Other words with pan- include pandemonium ("all the demons") and panacea ("all-healing").
