Εστιάζω στο πρόσωπο.

Εστιάζω means I focus or I am focusing.

In this sentence, εστιάζω σε / στο ... means to focus on .... So Εστιάζω στο πρόσωπο means I focus on the face / I am focusing on the face.

Greek present tense often covers both English simple present and present continuous, so the exact English translation depends on context.

Greek often leaves out subject pronouns when they are not needed.

The ending -ω in εστιάζω already tells you the subject is I. So Greek does not need εγώ unless the speaker wants emphasis.

• Εστιάζω στο πρόσωπο. = I focus on the face.
• Εγώ εστιάζω στο πρόσωπο. = I focus on the face. (more emphatic)

Στο is the contracted form of σε + το.

• σε = to, at, on, in depending on context
• το = the for a neuter singular noun

So:

• σε το πρόσωπο becomes στο πρόσωπο

This contraction is standard and very common in everyday Greek.

Here στο means on in English translation, because εστιάζω σε is the normal Greek pattern for focus on.

So although σε can have different meanings in different contexts, in this sentence:

• εστιάζω στο πρόσωπο = I focus on the face

You should learn εστιάζω σε as a set pattern.

Πρόσωπο is a neuter singular noun.

After σε, Greek uses the accusative case, so the noun should be in the accusative. For this noun, the nominative and accusative forms are the same:

• nominative: το πρόσωπο
• accusative: το πρόσωπο

So the form does not change visibly here, even though grammatically it is accusative after σε.

It can mean face, but it can also mean person in some contexts.

Common meanings include:

• face
• person
• sometimes figure or character, depending on context

In Εστιάζω στο πρόσωπο, the most natural meaning is usually the face, especially if you are talking about a photo, painting, camera, or visual attention.

But context is important, because Greek πρόσωπο is a flexible word.

A helpful approximation is:

es-tee-AH-zo sto PRO-so-po

The stressed syllables are:

• εστιάζω
• πρόσωπο

A few pronunciation notes:

• ζ sounds like z
• σ sounds like s
• ω is pronounced like o
• πρόσωπο has three clear syllables after pro-: pro-so-po

Yes, Greek often uses the definite article more regularly than English.

Here το πρόσωπο means the face. This usually sounds natural if you mean a specific face.

• Εστιάζω στο πρόσωπο. = I focus on the face.

If you remove the article and say Εστιάζω σε πρόσωπο, it sounds less natural in most everyday situations and changes the meaning toward something more general or less specific.

So for a specific object of attention, στο πρόσωπο is the normal choice.

It can mean both.

Greek present tense often covers:

• I focus
• I am focusing

So without more context, Εστιάζω στο πρόσωπο could mean either:

• a general action or habit
• an action happening right now

Context tells you which English version is best.

Yes. A very common alternative is:

Επικεντρώνομαι στο πρόσωπο.

This also means I focus on the face.

Very roughly:

• εστιάζω can sound a bit like focus
• επικεντρώνομαι can sound like concentrate/focus

Both are correct, but εστιάζω στο πρόσωπο is a perfectly natural sentence.
