Φοράω μάσκα στο νοσοκομείο.

Φοράω means I wear or I am wearing, depending on context.

It is the normal verb used for things you have on your body, such as:

• φοράω μάσκα = I wear / am wearing a mask
• φοράω παλτό = I wear / am wearing a coat
• φοράω γυαλιά = I wear / am wearing glasses

So in this sentence, it means that the speaker has a mask on in the hospital.

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

The ending of φοράω already tells you the subject is I. So:

• φοράω = I wear / I am wearing

You could say Εγώ φοράω μάσκα στο νοσοκομείο, but that would usually add emphasis, like I wear a mask at the hospital.

It can mean either one.

The Greek present tense often covers both:

• a general habit: I wear a mask in the hospital
• something happening now: I am wearing a mask in the hospital

Context tells you which meaning is intended.

Greek can leave out the indefinite article in cases like this, especially when the object is non-specific and the sentence is talking in a general way.

So:

• Φοράω μάσκα = I wear / am wearing a mask

If you said:

• Φοράω μια μάσκα

that would sound more like I am wearing one mask or would make the noun a bit more specific or concrete.

In everyday Greek, Φοράω μάσκα is very natural.

Στο is a contraction of:

• σε = in / at / to
• το = the

So:

• σε + το = στο

That is why στο νοσοκομείο means in the hospital or at the hospital.

In Greek, nouns after prepositions usually take the article much more often than in English.

So Greek normally says:

• στο νοσοκομείο = at / in the hospital

Even if English sometimes says in hospital or just uses a different article pattern, Greek usually wants the article here.

After σε / στο, Greek uses the accusative case.

So νοσοκομείο here is accusative. But νοσοκομείο is a neuter noun, and in this case its nominative and accusative singular forms are the same.

That is why you see:

• nominative: το νοσοκομείο
• accusative: το νοσοκομείο

Only the article and the grammar tell you the case; the noun itself looks the same here.

A rough pronunciation is:

fo-RA-o MAS-ka sto no-so-ko-MI-o

More closely:

• Φοράω = fo-RA-o
• μάσκα = MAS-ka
• στο = sto
• νοσοκομείο = no-so-ko-MI-o

The accent marks show where the stress goes:

• φοΡΑω
• ΜΑσκα
• νοσοκοΜΕΙο

Yes. Greek word order is more flexible than English.

The sentence:

• Φοράω μάσκα στο νοσοκομείο

is a neutral, natural way to say it.

But you could also say:

• Στο νοσοκομείο φοράω μάσκα

This puts more focus on in the hospital.

So the meaning stays basically the same, but the emphasis can change.

This is an important difference:

• φοράω μάσκα = I wear / I am wearing a mask
• βάζω μάσκα = I put on a mask

So:

• βάζω focuses on the action of putting it on
• φοράω focuses on having it on

In your sentence, φοράω is the correct choice because it describes the state of wearing the mask.
