Pronunciation

  • Classical: [prae̯.suːmp.tuˈoː.sʊs][1]
  • Ecclesiastical: [pre.s̬ump.tuˈɔː.s̬us][1]

Forms

praesūmptuōsus (feminine praesūmptuōsa, neuter praesūmptuōsum); first/second-declension adjective[1] The TLL takes praesumptiosus for the original spelling, found in the better manuscripts of Leo the Great, Sidonius, Claudianus Mamertus, Caesarius of Arles and Gregory of Tours;[2] praesumptuosus is printed in the scholia on Horace, Salvian, Gennadius and the Visigothic laws.[2]

Etymology

It is formed from Latin praesūmptiō (“presumption”) + -ōsus.[2][1] According to the TLL the original spelling was ⟨praesumptiōsus⟩, and manuscripts and editions waver towards ⟨praesumptuōsus⟩ under the influence of sūmptuōsus (“costly”).[2][3]

Earliest recorded meaning

The TLL dates the word from the 5th century.[2] Salvian uses it in De gubernatione Dei (435–439 AD) of those who rely too much on their own strength.[4][5][2]

Semantic evolution

It described people too sure of themselves and rash acts.[2] Sidonius Apollinaris has it in his letters.[6] In Medieval Latin it meant conceited or audacious, and also refractory or disobedient;[7] British writers from Alcuin on used it of presumptuous boldness, and as a noun for a presumptuous person.[8] Italian presuntuoso continues the Late Latin word,[9] and English presumptuous (mid-14th century) comes from Old French and directly from Late Latin.[3]

Timeline

  • 435–439 AD – Salvian uses it in De gubernatione Dei.[4][5][2]
  • c. 431–486 AD – Sidonius Apollinaris uses it in his letters.[6][4]
  • 967 – An English charter forbids any successor to take the land presumptuously.[8]
  • 1073 – Lanfranc uses it in a letter.[8]
  • mid-14th century – English borrows it as presumptuous.[3]
