Eta

The last letter of the word αὐτή is the eta.

Eta is the long "e" sound as in "obey." It is transliterated as an "e" with a line over the top of it: ē.

Eta is a vowel. It is the sixth vowel we have learned. What are the five we have learned? There is only one more vowel to go.

So how do you think you say, "She is my teacher"?

Interesting: the line over the "e" in the transliteration is called a "macron."
