Pronunciation

  • Classical: [ɪ.maː.ɡɪˈnaː.ri.ʊs][1]
  • Ecclesiastical: [i.ma.d͡ʒiˈnaː.ri.us][1]

Forms

imāginārius (feminine imāgināria, neuter imāginārium); first/second-declension adjective[1]

Etymology

It is from Latin imāgō (“image, likeness”) + -ārius.[2][1][3]

Earliest recorded meaning

The TLL records it from Livy and Seneca the philosopher on.[4][3] Livy uses it of sham insignia of power: they would not give way to imaginarii fasces, fasces that were a mere show.[5][6]

Semantic evolution

It means existing only in appearance or imagination: Seneca speaks of an empty honour of words (imaginarius honor verborum),[2] Suetonius of a fictitious kind of military service, and Florus of a stage king.[5][6] In law it is a fictitious, pretended act, such as the imaginaria venditio, the symbolic sale described by Gaius.[2][5]

The literal sense “of images” is found in an inscription about a funeral held with a lay figure,[2] and in the Edict of Diocletian for painters of figures.[5][6] As a noun, imāginārius is the soldier who carried the emperor's image as a standard, in Vegetius.[5][6] In Medieval Latin it also meant figurative, allegorical or symbolic, and concerned with pictures.[7][8] English imaginary (late 14th century) comes from it or from imagine with -ary.[9]
