Learn Hardcore Greek: Έκανα αναγγελία ζημιάς ηλεκτρονικά.

Yes, έκανα is the past form of κάνω, which literally means do / make. But in Greek, κάνω is also used in many expressions where English uses a more specific verb.

So έκανα αναγγελία ζημιάς literally looks like I made a damage report, but in natural English it is better understood as I filed / submitted a damage report.

This is very common in Greek:

κάνω αίτηση = submit/make an application
κάνω δήλωση = make/file a statement
κάνω κράτηση = make a reservation

So here έκανα is a normal and natural choice.

What tense is έκανα?

Έκανα is the past tense form of κάνω. More specifically, it is the aorist form used as a simple past in everyday Greek.
