Pronunciation

  • Classical: [oːˈmɪs.si.oː][1]
  • Ecclesiastical: [oˈmis.si.o][1]

Forms

ōmissiō f (genitive ōmissiōnis); third declension[1]

Etymology

It is formed from Latin ōmissus + -tiō,[1] the first part being the perfect passive participle of omittō (“to let go, leave out”).[1][2][3]

Earliest recorded meaning

Köbler's earliest source is Aurelius Victor (c. 360 AD),[4] who has it in the phrase omissio praedarum, the withholding of plunder.[5][6]

Semantic evolution

Lewis and Short call the word post-classical.[3] In Symmachus it is the leaving out of something, as of someone's praise, and in another of his letters the giving up of an accusation.[2][3] Rhetoricians used it for the figure in which a speaker says that he will not mention something and mentions it all the same: a treatise on figures transmitted under the name of Julius Rufinianus gives omissio as the Latin for this figure, and Tiberius Claudius Donatus speaks of a transition made “by omission”.[2][5][6]

In Christian Latin it became above all the failure to do what one ought.[7][1] Thomas of Chobham names two evils, doing wrong and omitting good, and medieval British writers also used it in law for the abandonment of a claim.[8] English took omission in the 14th century from Anglo-French and directly from Late Latin.[9]
