Pronunciation

  • Classical: [asˈsɪ.mɪ.lɪs][1]
  • Ecclesiastical: [asˈsiː.mi.lis][1]

Forms

assimilis (neuter assimile); third-declension two-termination adjective[1] Also spelled adsimilis.[2][3]

Etymology

It is formed from Latin ad- + similis (“like”).[2][4] De Vaan traces similis back to Proto-Italic *semali- (“alike, together”) and Proto-Indo-European *smh₂-el-i-.[4]

Earliest recorded meaning

Plautus has it with the genitive, in the Mercator: “as if you had never done anything like this deed”.[2][4]

Semantic evolution

It means “very like”, a strengthened similis.[2] It takes the genitive or the dative, or is followed by quasi.[2][3] Lewis & Short call it rare, mostly poetic and post-Augustan in prose, and found once in Cicero;[3] Lucretius, Virgil, Ovid and Suetonius use it.[2]

Timeline

  • c. 250–184 BC – Plautus uses it in the Mercator and the Truculentus.[2][5]
  • 96–55 BC – Lucretius uses it in assimili ratione “in a like manner”.[2][5]
  • 70–19 BC – Virgil uses it with the dative, of a black rock that seems about to fall.[2][5]
  • c. 75–c. 150 AD – Suetonius uses it with the dative.[2][5]
