Pronunciation

  • Ecclesiastical: [iɱˈfrak.t͡si.o][1]

Forms

īnfrāctiō f (genitive īnfrāctiōnis); third declension[1]

Etymology

It is formed from Latin īnfringō (“to break, weaken”) + -tiō.[2][3][1]

Earliest recorded meaning

Cicero uses it in the Tusculan Disputations in the phrase infractio animi, a crushed or broken spirit, which he pairs with demissio, despondency.[2][4][3]

Semantic evolution

In Late Latin it was also used of a physical breaking: Augustine speaks of the illusory “breaking” of an oar seen in water,[3] and the grammarian Priscian has it for a breaking to pieces.[4][3]

In Medieval Latin it became a legal term for forcible entry and burglary, for the fine paid for it, and for the breach of a peace, an immunity or a law.[5][6] British sources also use it for the fracture of a limb, the breaking of the voice, and, in infractio jejunii, the breaking of a fast, that is breakfast.[7]

Timeline

  • 81–43 BC – Cicero uses infractio animi for a broken spirit.[2][8]
  • 354–430 AD – Augustine uses it of the apparent bending of an oar.[3][8]
  • 6th century AD – Priscian uses it for a breaking to pieces.[4][8]
