Η παρτίδα αρχίζει με την τράπουλα και μία ζαριά.

No. Η here is the feminine singular definite article, meaning the.

In Modern Greek, η is pronounced ee, not like an English h. It is capitalized here only because it is the first word of the sentence. In the middle of a sentence, it would normally be η.

παρτίδα is a feminine singular noun, and here it is the subject of the sentence, so it appears in the nominative case: η παρτίδα.

Greek articles must agree with the noun in:

• gender
• number
• case

So:

• η = feminine singular nominative
• παρτίδα = feminine singular nominative noun

Depending on context, παρτίδα can mean things like game, round, hand, or even batch, but in this sentence it is the thing that begins.

αρχίζει is the 3rd person singular present tense of αρχίζω, which means to begin or to start.

So η παρτίδα αρχίζει means:

• the game begins
• the game starts

It is 3rd person singular because the subject η παρτίδα is singular.

Compare:

• αρχίζω = I begin
• αρχίζεις = you begin
• αρχίζει = he/she/it begins

με usually means with, and in this sentence it introduces the things the game starts with.

A very important grammar point is that με takes the accusative case in Modern Greek. That is why you get:

• την τράπουλα
• μία ζαριά

rather than nominative forms.

So the structure is:

• αρχίζει με ... = begins with ...

Because τράπουλα comes after με, and με takes the accusative case.

The noun τράπουλα is feminine singular, so:

• nominative: η τράπουλα
• accusative: την τράπουλα

That is why the article changes from η to την.

Also, τράπουλα usually means a deck/pack of cards, not just cards in general.

μία is the feminine form of one, and it can also work like a/an in English.

Since ζαριά is a feminine noun, the form has to be μία.

So:

• ένας = masculine
• μία / μια = feminine
• ένα = neuter

Because ζαριά is feminine, you say:

• μία ζαριά

not:

• ένα ζαριά

They are usually the same word in meaning. Both can mean one or a, depending on context.

• μία is the fuller spelling
• μια is very common in everyday writing

In careful or more formal writing, you may often see μία. The accent helps show the stress clearly.

So in this sentence, μία ζαριά and μια ζαριά would usually mean the same thing.

This is a very useful vocabulary distinction:

• ζάρι = die or dice
• ζαριά = a throw/roll of the die or dice

So:

• ένα ζάρι = one die
• μία ζαριά = one roll

That means the sentence is talking about the action/result of rolling, not about the physical die itself.

Because μία already fills that role.

In Greek, μία can function:

• as the numeral one
• or like the indefinite article a/an

So μία ζαριά naturally means one roll or a roll, depending on context.

You do not add a separate definite article there. Greek does not say something like η μία ζαριά here unless you specifically mean something like the one roll in a contrastive sense.

Yes. και means and, and both nouns belong to the same phrase introduced by με.

So the sentence structure is basically:

• με την τράπουλα και μία ζαριά
• with the deck and one roll

Greek often does not repeat the preposition before the second item if the meaning is clear.

You could repeat it for emphasis or clarity:

• με την τράπουλα και με μία ζαριά

but the original version is the more natural simple structure.

Yes. Greek word order is more flexible than English word order.

The sentence as given:

• Η παρτίδα αρχίζει με την τράπουλα και μία ζαριά

is a neutral, straightforward way to say it.

But Greek could also move things around for emphasis, for example:

• Με την τράπουλα και μία ζαριά αρχίζει η παρτίδα

That would still be understandable, but it sounds more marked or stylistic. For a learner, the original order is the safest and most natural pattern to remember.
