Questions & Answers about Όχι μόνο χρειάζονται ημερομηνία έκδοσης αλλά ελέγχουν και τόπο κατοικίας.

What does Όχι μόνο ... αλλά ... και ... mean in this sentence?

This is the Greek pattern for not only ... but also ...

In your sentence:

• Όχι μόνο χρειάζονται ημερομηνία έκδοσης
• αλλά ελέγχουν και τόπο κατοικίας

it means something like:

• They not only need an issue date, but they also check place of residence.

A few useful notes:

• όχι μόνο = not only
• αλλά = but
• και = also / too

Greek often uses αλλά και together for the second half of this structure, but the και can appear a little later in the clause, as it does here.

Why is there no explicit word for they?

Because Greek often leaves out subject pronouns when the verb ending already shows the person and number.

Here, both verbs are:

• χρειάζονται = they need
• ελέγχουν = they check

The endings tell you the subject is third person plural (they), so Greek does not need to say αυτοί unless it wants extra emphasis or contrast.

This is very common in Greek and is called pro-drop or subject omission.

Why does χρειάζονται look passive if it means they need?
