Actorul memorează scenariul.

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

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

So -ul here is basically the Romanian way of saying the.

The basic forms are:

• actor = actor
• a memora = to memorize
• scenariu = script

In the sentence, those become:

• actorul = the actor
• memorează = memorizes / is memorizing
• scenariul = the script

Memorează is the 3rd person singular present tense of a memora.

That means it matches a singular subject such as el = he, ea = she, or a singular noun like actorul.

So grammatically, it means:

• he memorizes
• she memorizes
• the actor memorizes

Depending on context, it can also mean is memorizing.

It can mean either one.

Romanian does not usually make the same clear distinction that English makes between:

• memorizes
• is memorizing

So Actorul memorează scenariul can mean:

• The actor memorizes the script
• The actor is memorizing the script

Context tells you which meaning is intended.

Mostly because of word order and meaning.

The normal Romanian order here is:

• subject + verb + object

So:

• Actorul = subject
• memorează = verb
• scenariul = direct object

In this sentence, the forms of actorul and scenariul do not visibly change to show subject vs. object, so Romanian relies a lot on the usual sentence order and context.

Because Romanian usually uses a suffixed definite article. In other words, instead of putting the before the noun, Romanian attaches it to the noun.

Compare:

• English: the actor

• Romanian: actorul

• English: the script
• Romanian: scenariul

This is one of the biggest structural differences from English.

Because scenariul is a direct object, but it is not a person.

Romanian often uses pe with specific human direct objects, for example with people. But with an inanimate thing like scenariul, you normally do not use pe.

So:

• Actorul memorează scenariul = correct

If the object were a specific person, pe would be much more likely.

Yes, often you can.

Romanian is a language that frequently allows the subject to be omitted when it is already clear from context. Since memorează already shows 3rd person singular, the listener may understand the subject from the situation.

So:

• Actorul memorează scenariul = The actor is memorizing the script
• Memorează scenariul = He/She is memorizing the script or The actor is memorizing the script, if the context makes it clear

English usually requires the subject, but Romanian often does not.

Yes, but Actorul memorează scenariul is the most neutral and natural order.

Romanian word order is more flexible than English, but changing it usually adds emphasis, contrast, or a special discourse effect.

For example, moving scenariul to the front could emphasize the script rather than the actor. In ordinary, neutral statements, though, subject + verb + object is the safest pattern.

So for a beginner, Actorul memorează scenariul is the best default version.

A rough pronunciation is:

• me-mo-REA-ză

The final ă is a very common Romanian vowel. It sounds somewhat like the weak vowel in English about or sofa.

So the last syllable is not a strong za, but more like:

• zuh, with a very short, light vowel

A rough full-sentence guide is:

• ac-TOR-ul me-mo-REA-ză sce-NA-ri-ul

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