Pronunciation

  • IPA (Classical): [ˈkas.soː][1]
  • IPA (Ecclesiastical): [ˈkas.so][1]

Forms

cassō (present infinitive cassāre, perfect active cassāvī, supine cassātum); first conjugation[1]

Etymology

It is from Latin cassus (“empty, void”) + -ō.[1][2][3] Etymonline instead traces Late Latin ⟨cassāre⟩ to quassō “to shake, quash”.[4]

Earliest recorded meaning

Gaffiot cites the Theodosian Code, of annulling, and Köbler lists Gregory of Tours.[3][5] Köbler dates Gregory 538/539–594 AD.[5]

Semantic evolution

Late Latin, it meant to bring to nothing, destroy, as in Sidonius, and in legal language to annul, make void, as in the Theodosian Code.[2][3]

In Ecclesiastical Latin it means to annul, make void, destroy.[6] English cassate (1510s, “to annul”) is from its participle cassātus.[4]

Timeline

  • 538/539–594 AD – Gregory of Tours uses it.[5]
  • 1510s – English cassate is recorded.[4]

Meanings

Verb

  1. To annul, make void.[3][6]
  2. To bring to nothing, destroy.[2]

Usage notes

The OLD's cassō is a Plautine word “to totter, begin to fall”, which it derives from cadō, and Lewis & Short and Wiktionary take it as a form of quassō.[7][2][1] Gregory of Tours also has an adverb cassō “in vain”.[3]
