Pronunciation

  • IPA (Classical): [ˈpuːr.ɡoː][1]
  • IPA (Ecclesiastical): [ˈpur.ɡo][1]

Forms

pūrgō (present infinitive pūrgāre, perfect active pūrgāvī, supine pūrgātum); first conjugation[1]

Etymology

It is from older ⟨pūrigō⟩, still in Plautus and Varro, from pūrus “pure” with the suffix -igō, as in fūmigō from fūmus.[2][3][1] Lewis and Short take it as a contraction of ⟨pūrum agō⟩ “to make pure”.[4] De Vaan instead derives it from a Proto-Italic *pūr “fire” and agō “to do”, first meaning “to lead the fire about”, and Gregory Nagy compares Umbrian ahtimem in a fire ritual.[1]

Earliest recorded meaning

The OLD's earliest citations are from Plautus, with the form pūrigō, and Cato, of cleaning and of medical purging.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant to clean, free from dirt, refine metals, as Cato's olives cleaned of leaves, of water and sky to clear, and to clear a space of weeds or debris, or of pests and undesirable persons.[2][4][6] It meant to husk, gut fish, stone fruit, and in medicine to purge the body, as in Cato.[2] It meant to purify ceremonially, as in Tibullus, to free from troubles, as in Lucretius, and in Plautus to clear oneself of an offence, apologize, atone.[2] From Cicero it meant to exonerate, justify, excuse, and to refute an accusation.[2]

In Ecclesiastical Latin it meant to purify, cleanse.[7] Through Old French purgier it gave English purge about 1300, first “to clear of a charge”, and Medieval Latin purgātōrium gave English purgatory.[8]
