Medicul imobilizează fractura.

Medic means doctor in the dictionary form.

Medicul means the doctor. Romanian usually puts the definite article at the end of the noun instead of using a separate word like English the.

• medic = doctor
• medicul = the doctor

So -ul is the masculine singular definite article here.

The dictionary form is fractură = fracture.

When it becomes definite, Romanian adds the definite article to the end:

• fractură = fracture
• fractura = the fracture

For many feminine nouns ending in -ă, the definite form changes -ă to -a.

Imobilizează is the present tense, 3rd person singular form of the verb a imobiliza = to immobilize.

So it means:

• he immobilizes
• she immobilizes
• it immobilizes

In this sentence, with medicul as the subject, it means the doctor immobilizes.

Mostly from word order and context.

The normal Romanian order here is:

Subject + Verb + Object

So:

• Medicul = the doctor → subject
• imobilizează = immobilizes
• fractura = the fracture → object

Also, semantically, it makes sense that the doctor performs the action.

In sentences like this, Romanian nouns often do not change form to clearly mark subject vs. direct object, so learners often rely on normal word order.

Romanian usually uses a postposed definite article, which means the article is attached to the end of the noun.

Compare:

• English: the doctor

• Romanian: medicul

• English: the fracture
• Romanian: fractura

So Romanian expresses definiteness, just not with a separate word before the noun.

Because fractura is an ordinary inanimate direct object.

Romanian often uses pe with personal direct objects, especially people:

• Văd medicul. = I see the doctor.
• Îl văd pe medic. = I see the doctor.
  (Here pe is common because it refers to a person.)

But with an inanimate noun like fractura, you normally just say:

• imobilizează fractura

So no pe is needed.

Yes, Romanian word order is more flexible than English, but Medicul imobilizează fractura is the most neutral and straightforward version.

If you change the order, the sentence may sound more marked, emphatic, or literary. For example, putting the object first often requires extra structure, such as a clitic:

• Fractura o imobilizează medicul.

That is much less neutral than the basic sentence. For beginners, Subject + Verb + Object is the safest pattern.

A practical pronunciation is:

ee-moh-bee-lee-ZEH-uh-zuh

A few helpful points:

• z sounds like English z
• ea in -zează is pronounced together, something like eah
• ă is the Romanian mid-central vowel, a short unstressed sound similar to the a in English sofa

You do not need to pronounce it exactly like English immobilize. Romanian stress and vowels are different.

It would be:

Un medic imobilizează o fractură.

That means:

• un medic = a doctor
• o fractură = a fracture

So the definite/indefinite contrast is:

• Medicul imobilizează fractura. = The doctor immobilizes the fracture.
• Un medic imobilizează o fractură. = A doctor immobilizes a fracture.

Often yes in medical contexts, but there is a useful distinction.

• medic specifically means a physician / medical doctor
• doctor can also mean doctor, but it may also refer to someone with a doctorate

So medic is the more precise word if you specifically mean a physician. That is why medicul is a very natural choice here.

Usually yes, especially in medical contexts, but Romanian may use it a little more naturally in phrases involving treatment of injuries.

So Medicul imobilizează fractura is natural Romanian medical wording, even if English might sometimes prefer something slightly different, such as The doctor stabilizes the fracture or immobilizes the injured area/limb, depending on context.

In other words, the Romanian sentence is normal, even if the most idiomatic English translation can vary a bit.
