  • IPA (Ecclesiastical): [ˈlap.sus][1]

Forms

lāpsus m (genitive lāpsūs); fourth declension[1]

Etymology

It is from Latin lābor (“to slip, fall”) + -tus, an action noun.[2][1]

Earliest recorded meaning

The OLD's earliest citation is Afranius, of slipping and falling, and Köbler's earliest source is Cicero.[2][3] Köbler dates Afranius to the second half of the 2nd century BC.[3]

Semantic evolution

It meant slipping and falling, a fall; any smooth or gliding motion, as of stars and rivers; a fall from favour or rank; and in Cicero a falling into error, a failing, lapse.[2][4]

In Ecclesiastical Latin it means falling, moral lapse, apostasy, and the passage of time.[5] Medieval Latin used it for a fish trap, a slide and the slipping by of time.[6] English lapse (mid-15th century) is from it through Old French, and German Lapsus “slip, error” is from it.[7][3]

Timeline

  • 2nd half of the 2nd century BC – Afranius uses it.[2][3]
  • 81–43 BC – Cicero uses it of a fall from favour and of error.[2][3]
  • mid-15th century – English lapse is recorded.[7]
