Recorded use
Wiktionary exampleThese source excerpts show how eta appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.
Greek was an exercise in making the familiar strange. Its alphabet mapped onto the Roman alphabet, but only partly so, and often letters did not sound how they looked — a rho (Ρ) was not a P, and an eta (Η) was not an H.
Etymology
From Ancient Greek ἦτα (êta).
