Stomatologul lucrează în cabinetul stomatologic.

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

• stomatolog = dentist / stomatologist

• stomatologul = the dentist

• cabinet = office / consulting room
• cabinetul = the office

So:

• Stomatologul = the dentist
• cabinetul stomatologic = the dental office

This is one of the biggest differences from English: Romanian often uses an attached definite article.

In Romanian, adjectives usually come after the noun.

So the normal order is:

• cabinet stomatologic = dental office
• cabinetul stomatologic = the dental office

This is much more natural than putting the adjective first. English usually says dental office, but Romanian prefers office dental in structure.

Because in Romanian, when a noun + adjective phrase is definite, the definite article is usually added to the noun, not separately to the adjective.

So:

• cabinet stomatologic = a dental office
• cabinetul stomatologic = the dental office

The -ul on cabinetul already makes the whole phrase definite.

Also, the adjective stomatologic agrees with the noun in gender and number:

• cabinet is masculine singular
• so the adjective is stomatologic (masculine singular)

Lucrează is the 3rd person singular present tense of the verb a lucra, meaning to work.

So:

• eu lucrez = I work
• tu lucrezi = you work
• el/ea lucrează = he/she works

In this sentence:

• Stomatologul lucrează = The dentist works

Romanian often does not need a separate subject pronoun like he or she if the noun is already there.

În usually means in or inside.

So:

• în cabinetul stomatologic = in the dental office

It emphasizes being inside that place.

English speakers may wonder about la, because Romanian also uses la very often for places. In many situations:

• la cabinet = at the office / to the office
• în cabinet = in the office

Here, în is a very natural choice because the sentence is describing where the person works, literally inside that office.

In this sentence, yes, stomatolog is basically dentist.

A few notes:

• stomatolog is the standard Romanian word
• in everyday English, the normal translation is usually dentist
• literally, it is related to stomatology, but learners should usually just understand it as dentist

So Stomatologul can be translated naturally as The dentist.

Because Romanian handles the differently from English.

English:

• the dentist
• the office

Romanian:

• stomatologul
• cabinetul

So Romanian does not normally use a separate word before the noun. Instead, it adds the article to the end of the noun.

This is called the enclitic definite article, and it is very common in Romanian.

You would remove the definite article:

• Stomatolog lucrează în cabinet stomatologic.

However, in real Romanian, you would more naturally say something like:

• Un stomatolog lucrează într-un cabinet stomatologic.

That means A dentist works in a dental office.

So compare:

• Stomatologul lucrează în cabinetul stomatologic. = The dentist works in the dental office.
• Un stomatolog lucrează într-un cabinet stomatologic. = A dentist works in a dental office.

Yes, it matters because Romanian adjectives and articles must agree with the noun.

In this sentence:

• stomatolog is masculine
• cabinet is masculine

That is why you get:

• stomatologul = masculine singular definite
• cabinetul = masculine singular definite
• stomatologic = masculine singular adjective form

If the noun were feminine, the forms would look different.

Stomatologic is an adjective meaning dental or related to dentistry/stomatology.

So:

• cabinet stomatologic = dental office
• literally, something like stomatological office

But in natural English, you would usually translate it as dental office, not stomatological office.

This is a good example of how Romanian sometimes uses a more technical-looking adjective where English prefers a simpler everyday word.

Yes, Romanian word order is somewhat flexible, but the normal order here is:

• Stomatologul lucrează în cabinetul stomatologic.

This is the most neutral and standard structure:

• subject: Stomatologul
• verb: lucrează
• place phrase: în cabinetul stomatologic

You could move things around for emphasis, but for a learner, the given order is the safest and most natural one to copy.

These are sounds English speakers often notice right away.

• ă in lucrează is a short central vowel, somewhat like the a in sofa
• â is a special Romanian vowel, a close central sound that English does not really have
• în contains that same Romanian î/â sound

Very roughly:

• lucrează ≈ loo-KREH-zuh
• în ≈ a short nasal-free central vowel, somewhat like uhn, but not exactly

You do not need a perfect accent immediately, but it helps to notice that ă and â/î are different sounds in Romanian.

Not in meaning.

In Romanian, cabinet often means:

• office
• consulting room
• practice room

So cabinetul stomatologic means the dental office or the dentist’s office, not a piece of furniture.

This is a very common false friend for English speakers.
