Στο ημίχρονο ο παίκτης πίνει νερό και ακούει τον προπονητή.

Στο means in the / at the here.

It is a contraction of:

• σε = in, at, to
• το = the (neuter singular)

So:

• σε το ημίχρονο → στο ημίχρονο

This contraction is very common in Greek:

• σε + τον → στον
• σε + την → στην
• σε + το → στο

In this sentence, Στο ημίχρονο means at halftime / during halftime.

Because the preposition σε normally takes the accusative case in Modern Greek.

The noun ημίχρονο is neuter singular. For many neuter nouns, the nominative and accusative forms are the same, so you see:

• το ημίχρονο = the halftime (nominative or accusative, same form)
• στο ημίχρονο = at/in the halftime

So even though a case change is involved after σε, the noun itself does not visibly change here.

Ημίχρονο means halftime.

It is a neuter noun:

• το ημίχρονο = the halftime

You will often hear it in sports contexts, especially football/soccer and basketball.

Ο παίκτης means the player.

Greek uses the definite article very regularly, often more regularly than English. Here:

• ο = the for a masculine singular noun in the nominative
• παίκτης = player

So:

• ο παίκτης = the player

This noun is the subject of the sentence, which is why it is in the nominative case.

Because Greek often drops subject pronouns when they are not needed.

The verb ending already tells you the subject is he/she/it:

• πίνει = he/she/it drinks / is drinking
• ακούει = he/she/it hears / listens

Since the sentence already has ο παίκτης as the subject, adding αυτός (he) would usually be unnecessary.

Πίνει is the 3rd person singular present tense of πίνω (to drink).

So:

• πίνω = I drink
• πίνεις = you drink
• πίνει = he/she/it drinks

In context, πίνει can mean:

• drinks
• is drinking

Greek present tense often covers both the simple present and the present continuous, depending on context.

Because Greek often leaves out the article with mass nouns or when speaking in a more general sense.

So:

• πίνει νερό = he drinks water / is drinking water
• πίνει το νερό = he drinks the water (a specific water, already known in context)

Here, νερό is being used in a general sense, so no article is needed.

Because τον προπονητή is the direct object of ακούει.

The dictionary form is:

• ο προπονητής = the coach (nominative, subject form)

But after a verb as a direct object, Greek uses the accusative:

• τον προπονητή = the coach (accusative, object form)

So the sentence shows:

• ο παίκτης = the player (subject)
• ακούει τον προπονητή = listens to / hears the coach (object)

This is a very common pattern in Greek:

• ο δάσκαλος → τον δάσκαλο
• ο φίλος → τον φίλο
• ο προπονητής → τον προπονητή

It can mean either, depending on context.

The verb ακούω can mean:

• hear
• listen to

So ακούει τον προπονητή could mean:

• he hears the coach
• he listens to the coach

In this sports context, he listens to the coach is often the more natural interpretation, but grammatically the Greek can cover both ideas.

Both are in the present tense and use the imperfective stem.

In practical learner terms, that means they describe an action as ongoing, repeated, or simply happening in the present.

So this sentence could be understood as:

• a general present: At halftime, the player drinks water and listens to the coach
• or a scene in progress: At halftime, the player is drinking water and listening to the coach

The exact English translation depends on context.

Greek word order is more flexible than English.

Starting with Στο ημίχρονο puts the time setting first:

• At halftime, the player drinks water and listens to the coach.

This is very natural in Greek. The sentence could also be rearranged, for example:

• Ο παίκτης πίνει νερό και ακούει τον προπονητή στο ημίχρονο.

But the original order sounds smooth and gives the listener the time context immediately.

A simple pronunciation guide would be:

Sto ee-MEE-hro-no o PEK-tis PEE-nee ne-RO ke a-KOO-ee ton pro-po-nee-TEE

A few helpful notes:

• ημίχρονο has the stress on μί
• παίκτης has the stress on παί
• νερό has the stress on the last syllable
• ακούει is pronounced with three syllables: a-KOO-ee
• προπονητή has the stress on the last syllable

It breaks down like this:

• Στο ημίχρονο = at halftime
• ο παίκτης = the player
• πίνει νερό = drinks water / is drinking water
• και = and
• ακούει τον προπονητή = listens to / hears the coach

So the structure is:

time expression + subject + verb + object + and + verb + object

This is a very common and useful Greek sentence pattern.
