Forms

effūsē (comparative effūsius, superlative effūsissimē); adverb[1]

Etymology

It is from Latin effūsus (“poured out; lavish”) + -ē, the adverb of that participle of effundō (“to pour out”).[1][2] De Vaan traces fundō (“to pour”) to Proto-Italic *χund- and Proto-Indo-European *ǵʰu-n-d- (“to pour”), comparing Ancient Greek χέω (khéō, “to pour”).[3]

Earliest recorded meaning

Köbler dates it from Cicero.[2] In his speech for Sextus Roscius a man gave many gifts generously and lavishly.[1]

Semantic evolution

It is over a wide area: Livy has a raid so widespread that nothing was left untouched.[1] In military contexts it is in disorder, in loose array: Sallust has men marching carelessly and in scattered order.[1] It is also without restraint or immoderately: Cicero calls someone so boundlessly insolent.[1] And it is lavishly or abundantly, as Cicero's gifts.[1]

Timeline

  • 81–43 BC – Cicero of lavish gifts and of boundless insolence.[1][2]
  • 86–34 BC – Sallust of men marching in loose order.[1][2]
  • 59 BC–17 AD – Livy of a widespread raid.[1][2]
