Pronunciation

  • IPA (Classical): [ˈɛk.spɫe.oː][1]
  • IPA (Ecclesiastical): [ˈɛk.sple.o][1]

Forms

expleō (present infinitive explēre, perfect active explēvī, supine explētum); second conjugation[1] Festus reports an old explenunt for explent.[2]

Etymology

It is from ex- “out, completely” and ⟨pleō⟩ “to fill”.[2][1]

Earliest recorded meaning

The OLD's earliest citations are from Plautus, of covering completely and of satisfying.[2] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

It meant to fill up a vessel, as in Lucretius, and in Plautus to fill all the space, and to satisfy someone's appetites.[2] In Cicero it meant to bring up to full measure, and to carry to completion.[2] In Propertius it meant to complete a period, suprēmum diem explēre to die, and in Ennius apparently to disembark.[2]

In Ecclesiastical Latin it meant to fill, fulfil, finish, complete.[4] Its derivative explētīvus “filling out” is behind English expletive.[1]

Timeline

  • 204–169 BC – Ennius uses it of disembarking.[2][3]
  • c. 250–184 BC – Plautus uses it of filling and satisfying.[2][3]
