Learn Hardcore Greek: Έστειλα την αίτηση τελευταία στιγμή. - I sent the application at the last minute.

The aorist is the normal Greek past tense for a single completed action. Here, the speaker is talking about one finished act of sending the application.

You may also notice the έ- at the beginning. This is a common past-tense augment in Greek verbs.

Why is there no word for I in the sentence?

Because Greek often does not need an explicit subject pronoun.

The ending of Έστειλα already tells you the subject is I. So Greek usually leaves out εγώ unless the speaker wants extra emphasis or contrast.

For example:

Έστειλα την αίτηση. = I sent the application.
Εγώ έστειλα την αίτηση. = I sent the application (with emphasis, maybe contrasting with someone else)

This is very normal in Greek.

Why is it την αίτηση and not η αίτηση?
