Το θεατρικό κείμενο έχει πρωταγωνιστικό ρόλο.

Because κείμενο is a neuter singular noun in Greek. The definite article has to match the noun in gender, number, and case.

Here:

• το = the for neuter singular
• κείμενο = a neuter singular noun
• θεατρικό also matches it, so it is neuter singular too

So:

• το κείμενο = the text
• το θεατρικό κείμενο = the theatrical text / the play text / the dramatic text

Because θεατρικό is an adjective agreeing with κείμενο.

The basic adjective is θεατρικός, θεατρική, θεατρικό:

• masculine: θεατρικός
• feminine: θεατρική
• neuter: θεατρικό

Since κείμενο is neuter, the adjective must also be neuter:

• το θεατρικό κείμενο

This is very common in Greek: adjectives change form to match the noun.

It literally means theatrical text, but in context it often means:

• play text
• dramatic text
• script of a play

So although the word-for-word meaning may sound a little formal in English, in Greek it is a natural phrase for a text intended for the theatre.

Yes. έχει is the 3rd person singular form of έχω (to have).

So:

• έχω = I have
• έχεις = you have
• έχει = he/she/it has

Since the subject is το θεατρικό κείμενο (the theatrical text), Greek uses έχει = has.

Because ρόλο is in the accusative case, which is used here for the direct object of έχει.

Compare:

• ο ρόλος = the role → nominative, used for the subject
• τον ρόλο / ρόλο = the role → accusative, used as the object

In this sentence:

• subject: Το θεατρικό κείμενο
• verb: έχει
• object: πρωταγωνιστικό ρόλο

So ρόλο is exactly what you would expect after a verb like has.

Greek often leaves out the article in expressions like this, especially when the phrase is more general or predicative in meaning.

So:

• έχει πρωταγωνιστικό ρόλο = has a leading role
• not necessarily has the leading role

If you added the article:

• έχει έναν πρωταγωνιστικό ρόλο = has a leading role
• έχει τον πρωταγωνιστικό ρόλο = has the leading role

The article changes the nuance. Without it, the phrase sounds natural and idiomatic.

It comes from πρωταγωνιστής (protagonist, main actor, leading figure) and means something like:

• leading
• principal
• starring
• central

So πρωταγωνιστικό ρόλο means:

• a leading role
• a central role

In this sentence, it does not necessarily mean acting on a stage literally. It can also mean that the dramatic text plays a very important or central part.

Because in Greek, adjectives often come before the noun, especially in standard, neutral phrasing.

So:

• πρωταγωνιστικό ρόλο = a leading role

Greek can sometimes place adjectives after the noun too, but before-the-noun is very normal and usually the most straightforward pattern for learners.

Good question. Grammatically, Greek says has:

• έχει πρωταγωνιστικό ρόλο

But in natural English, the idea is often closer to:

• plays a leading role
• has a leading role
• occupies a central role

So Greek uses have, where English may prefer play in many contexts.

A rough pronunciation guide is:

To theatrikó kímeno éhei protagonistikó rólo.

A few helpful points:

• θε in θεατρικό sounds like the in think, not this
• χ in έχει is a Greek sound with no exact English equivalent; after e/i it is softer, a bit like the h in huge for some speakers, but not exactly
• the stressed syllables are:
  • θεατρικό
  • κείμενο
  • έχει
  • πρωταγωνιστικό
  • ρόλο

Yes. Greek word order is more flexible than English because case endings help show what each word is doing.

The neutral order here is:

• Το θεατρικό κείμενο έχει πρωταγωνιστικό ρόλο.

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

• Πρωταγωνιστικό ρόλο έχει το θεατρικό κείμενο.

That version emphasizes πρωταγωνιστικό ρόλο more strongly.

Still, for learners, the original order is the safest and most neutral one.

Greek does have an indefinite article:

• ένας (masculine)
• μία / μια (feminine)
• ένα (neuter)

So Greek could say:

• έχει έναν πρωταγωνιστικό ρόλο

But very often Greek omits the indefinite article where English would use a. So:

• έχει πρωταγωνιστικό ρόλο is completely natural

This is something English speakers often notice: Greek does not use the indefinite article as automatically as English does.

Here are the dictionary forms:

• το → definite article, neuter singular
• θεατρικό → from θεατρικός (theatrical)
• κείμενο → κείμενο (text)
• έχει → from έχω (to have)
• πρωταγωνιστικό → from πρωταγωνιστικός (leading / central / starring)
• ρόλο → from ρόλος (role)

This is useful because Greek adjectives and nouns often appear in changed forms depending on gender, number, and case.
