Definitions
Estimated time of arrival, or the seventh letter of the Greek alphabet.
Word origin
From Ancient Greek ἦτα (êta).
Used in a sentence
“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.”
“We're even, as long as we're only counting today. Kilo 023, what's your ETA?”
