Pronunciation

  • Classical: [ˈɪm.pɪ.ɡɛr][1]
  • Ecclesiastical: [ˈim.pi.d͡ʒer][1]

Forms

impiger (feminine impigra, neuter impigrum, adverb impigrē); first/second-declension adjective (nominative masculine singular in -er)[1] It is also spelled inpiger.[2][3]

Etymology

It is from Latin in- (“not”) + piger (“sluggish”).[2][4][1] De Vaan traces piger to Proto-Italic *pig-ro- (“inactive”) and finds no etymology for the root.[5]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus.[5][6] Cicero uses it in the Verrines of a man who showed himself patient and active.[3]

Semantic evolution

It means not slothful: active, energetic, brisk or tireless, as Cicero's man active in writing letters.[2][3] Poets use it predicatively in an adverbial sense, as Virgil's “he eagerly drained the foaming bowl” and Horace's merchant who runs tirelessly to the farthest Indies.[2] Lucan applies it to the river Cephisus, and others to activities.[2] Church Latin glosses it diligent, industrious, quick.[7]
