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]
