Forms

taciturnitās f (genitive taciturnitātis); third declension[1]

Etymology

It is from Latin taciturnus (“silent, taciturn”) + -tās.[2][1] taciturnus is formed from taceō (“to be silent”),[3] which de Vaan traces to Proto-Italic *tak-ē- (“to be silent”) and Proto-Indo-European *tHk-eh₁- (“to be silent”).[4]

Earliest recorded meaning

De Vaan dates it from Plautus.[4] In Terence's Andria what is needed is fide et taciturnitate, “loyalty and silence”.[5]

Semantic evolution

It is the keeping of silence about something, and also a failure to write or send word.[2] Cicero speaks of the silence of witnesses and of the senate house, and of a man's slowness and reserve.[5] Horace has the silence of poets that would rob Romulus of his fame.[5] Georges separates plain silence from discretion as a virtue.[6] In British medieval Latin it is the silence of monastic life, as in Bede and Alcuin, and also an inability or refusal to speak.[7]

Timeline

  • c. 250–184 BC – Plautus has the noun.[4][3]
  • 190–159 BC – Terence, of keeping a secret.[5][3]
  • 81–43 BC – Cicero, of the silence of witnesses and of the senate.[5][3]
