Bărbatul vorbește despre crimă.

In Romanian, the definite article is usually attached to the end of the noun, not written as a separate word like English the.

So:

• bărbat = man
• bărbatul = the man

This is very common in Romanian:

• copil → copilul = the child
• oraș → orașul = the city
• bărbat → bărbatul = the man

So -ul here is the masculine singular definite article.

Vorbește is the 3rd person singular form of the verb a vorbi = to speak / to talk.

Because the subject is bărbatul = the man, Romanian uses the he/she/it verb form:

• eu vorbesc = I speak
• tu vorbești = you speak
• el/ea vorbește = he/she speaks

So:

• Bărbatul vorbește = The man speaks / is talking

Romanian often leaves out subject pronouns because the verb ending already shows the person.

So instead of saying:

• El vorbește despre crimă

Romanian can simply say:

• Vorbește despre crimă

And if you want to name the subject, you can say:

• Bărbatul vorbește despre crimă

The pronoun el = he is usually only added for emphasis, contrast, or clarity.

Despre means about or concerning.

It introduces the topic of speech, writing, thought, discussion, and so on.

Examples:

• vorbesc despre muzică = I’m talking about music
• citește despre istorie = he/she reads about history
• un film despre război = a film about war

So in your sentence:

• vorbește despre crimă = talks about crime

Crimă without the definite article usually means crime in a general sense.

• crimă = crime
• crima = the crime

So:

• despre crimă = about crime / about a crime
• despre crima = about the crime

In your sentence, crimă sounds more general unless the wider context makes it specific.

Also note that Romanian often uses the bare noun where English might use a more abstract noun phrase like about crime.

These two letters are very important in Romanian pronunciation.

• ă is a short, neutral vowel, similar to the a in English sofa for many speakers.
• ș is pronounced sh, like in shoe.

So roughly:

• Bărbatul ≈ BUHR-bah-tool
• vorbește ≈ vor-BESH-te
• crimă ≈ KREE-muh

These are only approximations, but they help at first.

A rough English-style pronunciation would be:

BUHR-bah-tool vor-BESH-te des-PREH KREE-muh

A few things to notice:

• the stress in bărbatul is on bat
• the stress in vorbește is on beș
• despre is usually pronounced clearly in two syllables
• crimă ends with that short neutral ă

Yes. Romanian word order is fairly flexible, although Subject + Verb + other information is the most neutral pattern.

The basic sentence is:

• Bărbatul vorbește despre crimă.

But you may also see:

• Despre crimă vorbește bărbatul.

That version puts more emphasis on despre crimă.

So the original sentence is the most straightforward, neutral order.

Because crimă here is not a direct object. It is part of the prepositional phrase despre crimă.

In Romanian, pe is often used with certain direct objects, especially definite human ones:

• Văd bărbatul = I see the man
• Îl văd pe bărbat = I see the man

But in your sentence:

• despre crimă = about crime

That is introduced by the preposition despre, so pe is not needed.

It can mean both, depending on context.

Romanian present tense often covers meanings that in English might be:

• speaks
• is speaking
• talks
• is talking

So:

• Bărbatul vorbește despre crimă could mean
  The man speaks about crime,
  The man is speaking about crime, or
  The man talks about crime,
  depending on context.

• bărbat is masculine
• crimă is feminine

That matters because Romanian articles and some related forms depend on gender.

For example:

• masculine definite singular often ends in -ul
  bărbat → bărbatul
• feminine definite singular often ends in -a
  crimă → crima

Learning the gender of each noun is very helpful in Romanian, because it affects articles and agreement.

Yes, but it means something slightly different.

• bărbatul = the man in the sense of an adult male
• omul = the man / the person / the human being, depending on context

So:

• Bărbatul vorbește despre crimă focuses on an adult male
• Omul vorbește despre crimă can sound broader or slightly different in nuance

If the intended meaning is specifically the man, then bărbatul is a very natural choice.
