Pronunciation

  • Classical: [kɔmˈma.kʊ.ɫoː][1]
  • Ecclesiastical: [komˈmaː.ku.lo][1]

Forms

commaculō (present infinitive commaculāre, perfect active commaculāvī, supine commaculātum); first conjugation[1]

Etymology

It is from Latin con- + maculō (“to stain”).[2][3][1] maculō is formed from macula (“spot, stain”), which de Vaan tentatively traces to Proto-Italic *smatlo- and Proto-Indo-European *smh₁-tlo- (“wiping”), comparing Ancient Greek σμάω (smáō, “to wipe clean”); he finds the connection possible, though a stain as a “smearing” is not a compelling semantic link.[4]

Earliest recorded meaning

Its earliest quotations are in Cicero and Sallust.[2][3] Cicero uses it of reputation: the TLL quotes sī Caelius sē istō īnfīnītō ambitū commaculāsset, “if Caelius had stained himself with that boundless canvassing”.[3][2]

Semantic evolution

Lewis and Short call it rare but classical.[5] Literally it means to stain deeply: Virgil has hands stained with the blood of children, and Tacitus altars of the gods stained with a man's own blood.[2][5] Statius uses it of ritual pollution.[2] Sallust and Tacitus use the participle of men defiled by crimes, and Sallust has it of sullying oneself by association with Jugurtha.[2][5] Valerius Maximus writes of someone who stained a whole village with the name of a crime.[2]

It lives on in Paulinus of Nola and the Theodosian Code,[5] and in Ecclesiastical Latin means to stain or pollute.[6]
