Pronunciation

  • Ecclesiastical: [ˈɛː][1]

Forms

ē (+ ablative)[1]

Etymology

It is the form of ex “out of” used before consonants.[2][1] De Vaan explains ⟨ē-⟩ from ⟨*egz-⟩, the variant of ⟨*eks⟩ before voiced consonants (⟨b d g l m n r⟩ and consonantal ⟨i u⟩).[3] The preposition is inherited from Proto-Italic *eks (“out”), inherited from Proto-Indo-European *h₁éǵʰs (“out”).[3][1]

Cognate with Oscan ee-, Umbrian ehe (“out of”), Ancient Greek ἐξ (ex, “out of”), Old Irish ess- (“out”) and Lithuanian iš (“out of, from”).[3][2]

Earliest recorded meaning

Plautus writes intereā ē portū nostra nāvis solvitur, “meanwhile our ship sets sail from the harbour”;[4] the preposition itself is found from the Twelve Tables and Livius Andronicus on.[3]

Semantic evolution

Ē has the senses of ex: “out of, from” in space, “from, since” in time, the material or source something comes from, and “in accordance with”.[4][2] As a prefix ē- appears in compounds such as ēveniō and ēdormiō.[2]

Timeline

  • c. 450 BC – The preposition ex is used in the Twelve Tables.[3][5]
  • c. 250–184 BC – Plautus: ē portū.[4][5]
  • 81–43 BC – Cicero writes ex and ē side by side: ex corporum vinculīs tamquam ē carcere.[4][5]

Meanings

Preposition

  1. (with ablative) out of, from (= ex, before consonants).[4][1]
  2. From, since (a time).[4]
  3. Of, made of; from among.[4]
  4. In accordance with;[4] ē rē pūblicā, in the public interest.[4]

Usage notes

Before vowels only ex is used; before consonants ex is also commoner than ē (in Cicero's Republic ē occurs 19 times and ex 61 times), and no rule decides between them.[4][2] Some phrases keep one form: ex parte, ex sententiā, ex tempore, but ē regiōne, ē rē nātā, ē vestīgiō and ē mediō.[4]

Ē is also the name of the letter E, an indeclinable neuter or feminine.[4][1]
