Pronunciation

  • Classical: [skruː.pʊˈɫoː.sʊs][1]
  • Ecclesiastical: [skru.puˈlɔː.s̬us][1]

Forms

scrūpulōsus (feminine scrūpulōsa, neuter scrūpulōsum); first/second-declension adjective[1]

Etymology

It is formed from Latin scrūpulus + -ōsus.[2][1] De Vaan files it under scrūpus, beside scrūpulus (“worry, precaution”), and finds no etymology for the family.[3]

Earliest recorded meaning

Lewis and Short quote a line of Pacuvius (220–130 BC) in which a cave is called scrūpulōsus, full of sharp stones;[4][5] de Vaan dates the word from Varro.[3]

Semantic evolution

Its literal sense was jagged, full of sharp points of rock: Cicero says his speech has sailed out from among such rocks.[2][4] From the Imperial period it was mostly used of minutely careful, anxious attention to detail, as in Valerius Maximus and Seneca.[2]

Christian Latin kept the sense exact, anxious, scrupulous.[6] Medieval British Latin also used it for curious or inquisitive,[7] and Du Cange records it for intricate, difficult questions.[8] English borrowed it in the mid-15th century as scrupulous.[9]
