Actorul citește scenariul.

Because Romanian usually puts the definite article at the end of the noun instead of using a separate word before it.

So:

• actor = actor
• actorul = the actor
• scenariu = script
• scenariul = the script

That is why Actorul citește scenariul already includes both instances of the.

That ending is the definite article attached to the noun.

For masculine and neuter singular nouns, the definite article is often:

• -ul after a consonant: actor → actorul
• -l attached after a final -u: scenariu → scenariul

So both words are definite, but the exact shape of the ending depends on how the base noun ends.

The dictionary form is a citi, meaning to read.

citește is the 3rd person singular present form, so it means:

• he reads
• she reads
• it reads

In this sentence, it matches actorul.

A few present-tense forms of a citi are:

• eu citesc = I read
• tu citești = you read
• el/ea citește = he/she reads
• noi citim = we read
• voi citiți = you all read
• ei/ele citesc = they read

In a simple neutral Romanian sentence, the usual order is:

subject + verb + object

So:

• Actorul = subject
• citește = verb
• scenariul = object

Romanian does not always mark the direct object with a special ending, so word order and context help a lot here.

Yes, but the original order is the most neutral and natural for a basic statement.

• Actorul citește scenariul. = neutral, standard
• Changing the order usually adds emphasis, contrast, or a special discourse effect.

For example, object-fronting is possible, but it often sounds incomplete without extra marking such as a clitic:

• Scenariul îl citește actorul.

That has a more marked meaning, something like emphasizing the script or contrasting the actor with someone else.

For beginners, Actorul citește scenariul is the safest default pattern.

Because in Romanian, many nouns have the same form for subject and direct object, especially in the singular.

So:

• actorul can be nominative
• scenariul can be accusative

But their forms do not change here.

Romanian does sometimes mark direct objects more clearly, especially with people or animate nouns, often using pe. For example:

• Actorul îl vede pe regizor. = The actor sees the director.

That does not happen in Actorul citește scenariul, because scenariul is an inanimate direct object.

It is neuter.

Romanian neuter nouns behave:

• like masculine in the singular
• like feminine in the plural

So in the singular, scenariu takes the same kind of definite article you would expect with a masculine-looking noun:

• scenariu = script
• scenariul = the script

Its plural is:

• scenarii = scripts
• scenariile = the scripts

You would say:

Un actor citește un scenariu.

Here:

• un actor = an actor
• un scenariu = a script

So unlike the definite article, the indefinite article is a separate word in Romanian.

No. Romanian usually does not need the subject pronoun if the verb form already makes the person clear.

So:

• Actorul citește scenariul is perfectly complete.
• El citește scenariul would mean He reads the script, with el added for emphasis, contrast, or clarity.

Romanian often drops subject pronouns in ordinary sentences.

Roughly: chee-TEHSH-teh

A few helpful pronunciation points:

• c before i sounds like English ch
• ș sounds like English sh
• the stress is on teș

So citește sounds approximately like chee-TEHSH-teh.

A rough English-style approximation is:

ak-TOR-ul chee-TEHSH-teh scheh-NA-ree-ul

A few notes:

• actorul has stress on TOR
• citește has stress on TEȘ
• scenariul is pronounced with all its vowels; the ending is not collapsed

This is only an approximation, but it is a useful starting point for an English speaker.

Because the sentence is talking about a specific actor and a specific script, not just any actor and any script.

So:

• Actorul = the actor
• scenariul = the script

Romanian, like English, can make both the subject and the object definite if both are understood as specific. There is nothing unusual about having the definite article on both nouns in the same sentence.
