Pronunciation

  • Classical: [wa.keːˈfiː.oː][1]
  • Ecclesiastical: [va.t͡ʃeˈfiː.o][1]

Forms

vacēfīō (present infinitive vacēfierī); third conjugation, semi-deponent, no supine stem, irregular long ī[1]

Etymology

According to the OLD it is from Latin vacuus (“empty”) + fīō (“to become”), comparing vacuēfaciō (“to make empty”).[2] Wiktionary thinks it more likely to come from a lost stative verb *vacēō (“to be empty”) with ⟨fīō⟩, like calvēfīō.[1]

Earliest recorded meaning

Lucretius uses it twice, both in book 6: multusque vacēfit in mediō locus, “and much space becomes empty in between”.[3][4]

Semantic evolution

Lewis & Short know it only from these two lines of Lucretius,[3] and Georges treats it under vacuēfaciō.[5]

Timeline

  • 96–55 BC – Lucretius uses it twice.[3][4][6]

Meanings
