Pronunciation

  • Classical: [sɪ.mɪ.lɪˈtuː.doː][1]
  • Ecclesiastical: [si.mi.liˈtuː.do][1]

Forms

similitūdō f (genitive similitūdinis); third declension[1]

Etymology

It is formed from Latin similis (“like”) + -tūdō.[2][1][3] De Vaan traces ⟨similis⟩ to Proto-Italic *semali- (“alike, together”) and Proto-Indo-European *smh₂-el-i-; it is cognate with Old Irish samail (“likeness”), Welsh hafal (“like”) and Ancient Greek ὁμαλός (homalós, “level”).[4]

Earliest recorded meaning

De Vaan gives Pacuvius as its first author.[4] In a tragedy of his a character recognises someone vōcis … similitūdine, by the likeness of the voice.[2]

Semantic evolution

It is likeness or resemblance, with similitūdō vērī the appearance of truth, probability (Cicero), a shared nature, and ad similitūdinem “after the manner of”.[2] It is also something that resembles another thing, a likeness in a painting or statue (Velleius), the use of a parallel case, a comparison, simile or analogy, which the Rhetorica ad Herennium defines as a figure of speech, and sameness or monotony, which Cicero calls the mother of satiety.[2][3]

Church Latin glosses it “likeness, parable”,[5] and medieval Latin used it for an example, comparison or parable.[6] English similitude (late 14th century) comes from it, partly through Old French.[7]
