Forms

epidēmicus (feminine epidēmica, neuter epidēmicum); first/second-declension adjective[1] Medieval spellings include effidemicus and epidimicus.[2][1]

Etymology

It is from Latin epidēmia + -icus.[2][1]

Earliest recorded meaning

It first appears in the second half of the 12th century,[1] in Maurus' commentary on the Hippocratic Prognostics, where it renders a form of Ancient Greek ἐπιδημέω (epidēméō) and is explained as “long” illnesses; the MLW gives the sense widespread, rampant.[2]

Semantic evolution

In British sources it is found in Gerald of Wales.[3] Neo-Latin writers such as Francis Bacon and William Camden use it of contagions and, figuratively, of a sickness of minds that spreads widely.[4]

Timeline

  • 2nd half of the 12th century – Maurus uses it in his commentary on Hippocrates.[2][1]
  • 1580 – William Camden writes of an epidemica contagio in his annals for that year.[4]
