Pronunciation

  • Classical: [ˈɛf.fɔr][1]
  • Ecclesiastical: [ˈɛf.for][1]

Forms

effor (present infinitive effārī, perfect active effātus sum); first conjugation, deponent[1] It is defective: the forms in use are a few of the present and future, the perfect effātus, the imperative and the infinitive.[2][3] It is also spelled ecf-.[2]

Etymology

It is from Latin ex- + for (“to speak”).[2][4] De Vaan traces ⟨for⟩ to Proto-Italic *fā- (“to speak”) and Proto-Indo-European *bʰeh₂- (“to speak”), cognate with Umbrian fato (“said”) and Ancient Greek φημί (phēmí, “I say”).[5]

Earliest recorded meaning

The OLD's earliest example is Ennius' Annals: “having uttered these words the father withdrew”.[2]

Semantic evolution

It is “to utter, speak out”, especially solemn words, and to declare: Livy has the view that it was wrong to reveal what should be hidden.[2] Cicero uses it of stating a proposition, and Virgil's Dido begins to speak and stops mid-word.[2] As a word of the augurs it means to mark out by a spoken formula the space in which signs are watched: Varro says the augurs fixed the limit of the auspices outside the city.[2][1]

Church Latin glosses it “utter, speak out”.[6]

Timeline

  • 204–169 BC – Ennius of words spoken.[2][7]
  • 116–27 BC – Varro of the augurs' formula.[2][7]
  • 81–43 BC – Cicero of stating a proposition.[2][7]
  • 70–19 BC – Virgil of Dido beginning to speak.[2][7]
