Pronunciation

  • Classical: [am.plɪˈtuː.doː][1]
  • Ecclesiastical: [am.pliˈtuː.do][1]

Forms

amplitūdō f (genitive amplitūdinis); third declension[1]

Etymology

It is from Latin amplus (“large, ample”) + -tūdō.[2][3] De Vaan derives ⟨amplus⟩ from Proto-Italic *am-lo- (“seizable”), from a root Proto-Indo-European *h₃emh₃- (“to grab”), with /ml/ becoming /mpl/ as in exemplum; he notes problems with the early loss of the vowel.[4]

Earliest recorded meaning

The OLD's earliest examples are the Rhetorica ad Herennium, on the dignity and greatness of the state, and Varro, on the size of animals' limbs.[2]

Semantic evolution

Its physical sense is size, bulk, extent, and also abundance;[2][5] Lewis and Short note that it is a prose word.[2][5] Figuratively it is distinction, eminence, prestige, as of the state or a magistracy, greatness of mind (which Cicero calls the finest thing of all), and the importance of a subject.[2] In rhetoric it is the grandeur of style produced by sonorous rhythms, and amplification of an argument.[2]

Church Latin glosses it “breadth, width, amplitude; distinction”.[6] English amplitude (1540s) comes from it, partly through French.[7]

Timeline

  • 86/82 BC – the Rhetorica ad Herennium of the greatness of the state.[2][8]
  • 116–27 BC – Varro of size.[2][8]
  • 81–43 BC – Cicero of greatness of mind.[2][8]
  • c. 35–95/96 AD – Quintilian of a grand style.[2][8]
  • 1540s – English amplitude.[7]
