Etymology[edit]

Derived from its majuscule counterpart Ε, from the Phoenician letter 𐤄, he.

Letter[edit]

ε (e) (lowercase, uppercase Ε)

  1. Lower case epsilon, the fifth letter of the ancient and modern Greek alphabets. Its name was εἶ, later ἒ ψιλόν, and presently έψιλον. It represents the same sound in both alphabets, a somewhat lowered variant of the mid front unrounded vowel: IPA(key): /e/ or /e̞/. It is preceded by δ and followed by ϝ.
