Astăzi lucrez de acasă pe laptop, pentru că la birou este prea aglomerat.

Romanian often drops subject pronouns when they are not needed, because the verb ending already shows the subject.

• lucrez = I work
• the ending -ez tells you it is 1st person singular

So Astăzi lucrez... is perfectly natural. You can add eu if you want emphasis or contrast:

• Eu lucrez de acasă, dar colegul meu merge la birou.

Lucrez is the present tense, 1st person singular form of a lucra = to work.

A few present-tense forms are:

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

So in this sentence, lucrez means I am working / I work, depending on context. Romanian present tense can cover both ideas.

Yes. Romanian word order is fairly flexible, and putting Astăzi first gives extra emphasis to today.

You could also say:

• Lucrez astăzi de acasă...
• De acasă lucrez astăzi...

But Astăzi lucrez... sounds very natural if the speaker wants to frame the whole sentence around today.

Also, astăzi and azi both mean today. Azi is shorter and very common in speech.

Both are possible, but they are not exactly the same.

• acasă = at home
• de acasă = from home

In modern Romanian, a lucra de acasă is the common expression for to work from home in the remote-work sense.

Compare:

• Lucrez acasă. = I work at home.
• Lucrez de acasă. = I work from home.

The second one more clearly suggests that home is the place from which you are doing your job instead of going elsewhere.

Because de acasă is the idiomatic expression here.

• de acasă = from home
• din casă = out of the house / from inside the house

So lucrez de acasă means I work from home, while din casă would sound much more literal and physical, not like the normal expression for remote work.

Yes, but in Romanian pe is often used with devices to mean on / using that device.

So:

• lucrez pe laptop = I work on a laptop
• lucrez pe calculator = I work on the computer
• vorbesc pe telefon = I talk on the phone

It does not mean you are physically sitting on top of the laptop. It is just the normal Romanian way to express using that device.

Pentru că is the standard way to say because.

• pentru că = because
• că usually = that

So in this sentence, pentru că introduces the reason:

• ...pentru că la birou este prea aglomerat.

You may also see fiindcă or deoarece, which can also mean because, but pentru că is extremely common and natural.

This is an important distinction.

• la birou = at the office, at work, in the office environment in general
• în birou = in the office room, physically inside an office

In your sentence, la birou is more natural because it means the workplace in general is too crowded. If you said în birou, it would sound more like you are talking about being inside a particular room.

After many prepositions, Romanian often uses a noun without the definite article when talking about a place in a general sense.

So:

• la birou = at the office
• la școală = at school
• la bancă = at the bank

If you wanted a specific office, you would usually add more information:

• la biroul meu = at my desk / office
• la biroul directorului = at the director’s office

So la birou here means at the office in a general, everyday sense.

Yes, e would also be correct.

• este = is
• e = is

They mean the same thing. Este is a little fuller and can sound slightly more careful or neutral, especially in writing. E is very common in speech.

So both are natural:

• la birou este prea aglomerat
• la birou e prea aglomerat

Prea means too, and aglomerat means crowded, busy, or congested, depending on context.

In this sentence, prea aglomerat suggests that the office is uncomfortably full, busy, or hectic. It does not only refer to people physically packed together; it can also give the idea of too much activity, noise, or traffic.

Aglomerat is the masculine singular form of the adjective.

That form fits well here because:

• birou is a neuter noun
• in the singular, Romanian neuter nouns behave like masculine for adjective agreement

So if you think of it as describing birou, the form aglomerat makes sense.

Also, Romanian often uses expressions like e aglomerat, e cald, e frig in a somewhat impersonal way, similar to it is crowded, it is hot, it is cold.

In standard Romanian punctuation, a clause introduced by pentru că is commonly separated with a comma from the main clause, especially when it comes after it.

So this is normal:

• Astăzi lucrez de acasă pe laptop, pentru că la birou este prea aglomerat.

Romanian generally uses commas before subordinate clauses more readily than English does, so this comma may feel more natural in Romanian than it would in English.
