Etymology

viral = vir<virus> + al<adjective suffix>

  • vir <virus>: From Latin virus (poison, slime, venom), later adopted in biology to mean "infectious agent."
  • al <adjective suffix>: A suffix of Latin origin used to form adjectives meaning "pertaining to" (e.g., natural, digital).

Etymology Origin:
The word viral originates from the Latin virus, which initially referred to poisonous substances. By the 18th century, virus gained its modern biological meaning as a microscopic infectious agent. The suffix -al was added to form the adjective viral, first used in medical contexts (e.g., viral infection). In the 21st century, viral expanded metaphorically to describe digital content spreading rapidly, akin to a biological virus.
