Questions & Answers about Αν δεν αερίζεις καλά το δωμάτιο, το ταβάνι και οι τοίχοι κρατάνε υγρασία.

What does Αν mean here, and how is it used?

Αν means if.

In this sentence, it introduces a condition:

• Αν δεν αερίζεις καλά το δωμάτιο... = If you don’t air out the room well...

This is the normal word for if in modern Greek when talking about a condition.

Why is it δεν αερίζεις and not some infinitive form like in English?

Modern Greek does not use the infinitive the way English does.

So instead of something like if not to air the room, Greek uses a fully conjugated verb:

• αερίζεις = you air / you ventilate
• δεν αερίζεις = you do not air / you don’t ventilate

Greek usually expresses actions with personal verb forms, not infinitives.

What exactly does αερίζεις mean?

αερίζω means to air, to air out, or to ventilate.

So:

• αερίζεις = you air out / you ventilate

In this sentence, it means opening windows or otherwise letting fresh air circulate in the room.

Why is αερίζεις in the second person singular?
