Ο διαιτητής σφυρίζει και το παιχνίδι αρχίζει.

Greek normally uses the definite article much more often than English.

• Ο διαιτητής = the referee
• το παιχνίδι = the game / the match

So in natural Greek, the articles ο and το sound normal here. Leaving them out would usually sound unnatural unless you were speaking in a very special style, like headlines or notes.

Word by word:

• Ο = the (masculine singular)
• διαιτητής = referee
• σφυρίζει = whistles / blows the whistle
• και = and
• το = the (neuter singular)
• παιχνίδι = game / match
• αρχίζει = begins / starts

So the structure is very close to English: The referee whistles and the game begins.

Because Greek articles change according to gender, number, and case.

In this sentence:

• ο is the masculine singular nominative article, used with διαιτητής
• το is the neuter singular nominative article, used with παιχνίδι

So:

• ο διαιτητής = masculine noun
• το παιχνίδι = neuter noun

Unlike English, Greek nouns belong to grammatical genders, and the article has to match the noun.

They are both in the nominative case because they are the subjects of their verbs.

• Ο διαιτητής σφυρίζει = the referee whistles
• το παιχνίδι αρχίζει = the game begins

In both parts, the noun is doing the action, so nominative is used.

Both σφυρίζει and αρχίζει are third person singular present tense forms.

That means they correspond to:

• he/she/it whistles
• he/she/it begins

Here the subjects are:

• ο διαιτητής → he / the referee
• το παιχνίδι → it / the game

So the verbs are in the form used for he, she, it.

Because Greek often does not need subject pronouns. The verb ending already tells you the person and number.

For example:

• σφυρίζω = I whistle
• σφυρίζεις = you whistle
• σφυρίζει = he/she/it whistles

Since σφυρίζει already shows third person singular, Greek usually does not need a separate pronoun like he. The noun ο διαιτητής is enough.

The same is true for αρχίζει.

It can mean both, depending on context.

The verb σφυρίζω basically means to whistle. But with a referee as the subject, it naturally means to blow the whistle.

So in this sentence, a Greek speaker understands: The referee blows the whistle, and the game begins.

That is a normal, natural use of the verb.

Yes. Αρχίζει means begins or starts.

So:

• το παιχνίδι αρχίζει = the game begins
• It could also be translated as the game starts

English may choose begins or starts depending on style, but the Greek verb is perfectly natural here either way.

Greek uses the present tense here just like English can.

This sentence describes an action happening right now or as part of a live sequence:

• The referee whistles
• the game begins

This is very common in commentary, narration, or describing a regular sequence of events.

So the Greek present here is straightforward and natural.

Yes, Greek word order is more flexible than English, because case endings and verb forms carry a lot of grammatical information.

The neutral, natural order here is:

Ο διαιτητής σφυρίζει και το παιχνίδι αρχίζει.

But Greek can shift word order for emphasis, for example:

• Σφυρίζει ο διαιτητής και αρχίζει το παιχνίδι.

That still makes sense, but it may sound more like narration or emphasis. For a learner, the original order is the safest and most standard one.

A simple pronunciation guide:

• Ο ≈ o as in not (short)
• διαιτητής ≈ thee-eh-tee-TEES
• σφυρίζει ≈ sfee-REE-zee
• και ≈ keh
• το ≈ to
• παιχνίδι ≈ pehkh-NEE-thee
• αρχίζει ≈ ar-KHEE-zee

A rough full reading:

o thee-eh-tee-TEES sfee-REE-zee keh to pehkh-NEE-thee ar-KHEE-zee

A few notes:

• χ is a throaty sound, not an English k
• θ in Modern Greek sounds like th in this
• the capitalized syllable shows the stress

The accent mark shows which syllable is stressed.

• διαιτητής → stress on the last syllable
• σφυρίζει → stress on -ρί-
• παιχνίδι → stress on -νί-
• αρχίζει → stress on -χί-

Stress matters in Greek pronunciation, so learners should pay attention to these marks. They are not optional in normal written Greek.

It literally means game, but in context it can also be understood as match.

So with sports:

• το παιχνίδι αρχίζει can mean the game begins
• and depending on the sport, English might naturally say the match begins

Greek often uses παιχνίδι in sports contexts where English could use either game or match.

Yes — that is very important in Greek.

It is best to learn nouns together with their article:

• ο διαιτητής not just διαιτητής
• το παιχνίδι not just παιχνίδι

That helps you remember:

• the noun’s gender
• the correct form of the
• how adjectives and other words will agree with it later

This is one of the best habits for learning Greek vocabulary.
