Șoferul frânează.

Because Romanian usually puts the definite article at the end of the noun, not before it.

• șofer = driver
• șoferul = the driver

So -ul here is the masculine singular definite article, attached directly to the noun.

This is one of the biggest differences from English:

• English: the driver
• Romanian: șoferul

Romanian normally uses a postposed definite article, meaning the article is added to the end of the noun.

So instead of:

• English: the + driver

Romanian has:

• șofer + ul = șoferul

This is completely normal in Romanian:

• băiatul = the boy
• omul = the man
• șoferul = the driver

Frânează is the 3rd person singular present tense of the verb a frâna, meaning to brake.

So frânează can mean:

• he brakes
• she brakes
• it brakes
• or, with a noun subject, the driver brakes / is braking

In this sentence:

• Șoferul frânează. = The driver brakes / is braking.

It can mean either one, depending on context.

Romanian present tense often covers both:

• the simple present: brakes
• the present continuous: is braking

So Șoferul frânează. could mean:

• The driver brakes.
• The driver is braking.

Usually the situation tells you which meaning is intended.

Because Romanian does not need a separate verb like is to make the present continuous in this kind of sentence.

English says:

• The driver is braking

Romanian simply uses the present tense:

• Șoferul frânează

So Romanian often uses one present form where English chooses between:

• brakes
• is braking

Romanian often leaves out subject pronouns because the verb ending already gives information about the subject.

frânează is a 3rd person singular form, so it already tells you the subject is:

• he
• she
• it
• or a singular noun like șoferul

That is why Șoferul frânează sounds complete by itself.

You could add a pronoun in other contexts, but it is often unnecessary.

A rough English-friendly guide is:

șoferul ≈ sho-FEH-rul
frânează ≈ fruh-NEA-zuh

A few key sounds:

• ș = sh as in shoe
• ă = a short neutral vowel, like the a in sofa
• â = a Romanian vowel with no exact English equivalent; it sounds somewhat like a deep central uh
• z is pronounced like English z

The stress is approximately:

• șoFERul
• frâNEAză

They show different sounds:

• Ș ș = sh
  • Șoferul starts with sh
• ă = a short, neutral vowel, like the unstressed vowel in sofa
  • heard at the end of frânează
• â = a central vowel specific to Romanian
  • found in frânează

These marks are not optional in correct Romanian spelling, because they distinguish real sounds and sometimes different words.

Yes. Șofer is a masculine noun, and șoferul is its masculine singular definite form.

So:

• un șofer = a driver
• șoferul = the driver

If you were talking about a female driver, Romanian often uses:

• șoferița = the female driver / driver (female, depending on context)

But in modern usage, șofer can also sometimes be used more generally depending on context.

Yes, Romanian word order is somewhat flexible, though Șoferul frânează is the most neutral and basic order.

This is:

• subject + verb

You may also see other orders for emphasis or in special contexts, for example:

• Frânează șoferul.

That can sound more marked, literary, or context-dependent. For a learner, the safest default is:

• Șoferul frânează.

The dictionary form is a frâna, which means to brake.

Romanian verbs are usually listed with a + verb:

• a frâna = to brake
• a merge = to go
• a vedea = to see

From a frâna, you get:

• frânez = I brake
• frânezi = you brake
• frânează = he/she/it brakes

It is singular.

More exactly, it is 3rd person singular.

So it matches a singular subject like:

• șoferul = the driver

If the subject were plural, the verb would change:

• Șoferii frânează. = The drivers are braking / brake.

Interestingly, in this verb form, 3rd person singular and 3rd person plural can look the same:

• el/ea frânează
• ei/ele frânează

So the noun or context tells you whether it is singular or plural.

Yes, you should pronounce it.

In șoferul, the ending -ul is the definite article, and the l is part of that ending.

So:

• șofer = driver
• șoferul = the driver

In careful standard pronunciation, the l is pronounced. Learners should definitely keep it.

Yes. That would mean:

• A driver is braking / A driver brakes

Here:

• un = a/an
• șofer = driver

So compare:

• Șoferul frânează. = The driver is braking.
• Un șofer frânează. = A driver is braking.

The difference is definiteness:

• șoferul = a specific, known driver
• un șofer = any driver / an unspecified driver
