  • Ecclesiastical: [ˈflaː.ɡrum], [ˈflaɡ.rum][1]

Forms

flagrum n (genitive flagrī); second declension[1]

Etymology

It is inherited from Proto-Italic *flagro- (“whip”), perhaps inherited from Proto-Indo-European *bhlHg-ro-.[2] De Vaan connects it with flāgitō (“to demand”), an iterative of an unattested verb meaning “to whip as a punishment”, whence “to scold”; he compares Old Norse blak (“a blow”) and Lithuanian blokšti (“to swing back and forth”), but calls these cognates uncertain.[2][3]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[2][4] who has a threat to make someone hot with lashes, faciam ferventem flagris.[3]

Semantic evolution

It is a whip or lash used for punishment, and also a stroke of the whip or a flogging.[3][5] Plautus has “I'll fill you with lashes”, and calls a slave a gymnasium flagrī, a training ground for the whip;[3][5] Titinius has slaves whose skin is cut up by the lash.[5] Livy, Suetonius and Juvenal use it, and Juvenal speaks of a man who led the conquered Romans to his whips, that is, to servitude.[5] Köbler records it in medieval texts from the 8th–9th century.[4]

Timeline

  • c. 250–184 BC – Plautus, of threats of the lash.[3][5][4]
  • 59 BC–17 AD – Livy.[5][4]
  • c. 67–c. 127 AD – Juvenal, of servitude.[5][4]
