Questions & Answers about Πρόσεχε στο μπάνιο, γιατί γλιστράει το πάτωμα.

What does Πρόσεχε mean exactly?

Πρόσεχε means be careful, watch out, or pay attention depending on context. It comes from the verb προσέχω, which means to pay attention, to be careful, or to watch out for something.

Why is it Πρόσεχε and not Πρόσεξε?

This is a very common Greek question because Greek imperatives often show aspect.

• Πρόσεχε is the imperfective imperative. It suggests an ongoing or general warning: Be careful.
• Πρόσεξε is the perfective imperative. It often sounds more like a one-time warning: Watch out! / Be careful right now!

In this sentence, Πρόσεχε στο μπάνιο sounds like a general caution about the situation in the bathroom.

Who is being spoken to here, and where is the word for you?

Πρόσεχε is addressed to one person in the informal singular. Greek usually does not need to say the pronoun you, because the verb ending already shows who the subject is.

So the sentence naturally leaves out εσύ. If you were speaking to more than one person, or using the polite/formal form, you would say Προσέχετε.
