Forms

pestilentia f (genitive pestilentiae); first declension[1]

Etymology

It is from pestilēns “unhealthy, pestilent” with the suffix -ia, from pestis “plague”.[2][1][3] De Vaan rejects the old explanation of ⟨pestis⟩ from ⟨*per-sitis⟩ and notes a possible Avestan ⟨*pesti-⟩ “illness” in the name of a disease.[4]

Earliest recorded meaning

The OLD's earliest citation is from Varro, of an epidemic.[2] Köbler dates Varro 116–27 BC.[5]

Semantic evolution

It meant an outbreak of epidemic disease, a plague, as in Varro, and in Cicero the unhealthiness of air or land.[2] Lewis & Short add figurative uses for a pernicious influence.[6]

British Medieval Latin used it for an outbreak of deadly disease, especially the plague of 1348–9, and it served as a reference point for dates.[7] It survives in Italian pestilenza and Spanish pestilencia, and through Old French pestilence it gave English pestilence about 1300.[1][3]
